MCQ (Multiple Choice Questions)
1. His father is three times his son Ronit’s age. He’d be two and a half times Ronit’s age after eight years. How many times would he be Ronit’s age after another 8 years? a. 2 times b. 2 1/2times c. 2 3/4times d. 3 times
Answer: A
Explanation: Let’s say Ronit is currently x years old. Then, father’s current age is equal to (x + 3x) years, which equals 4x years. (x + 8) = (4x + 8) = 5/2.5x + 40 = 8x + 16,24 x 3,x equals 8.As a result, the necessary ratio is (4x + 16)/(x + 16) = 48/24 = 2.
2. The total age of five children born at three-year intervals is 50 years. What is the youngest child’s age? a. 4 years b. 8 years c. 10 years d. None of these
Answer: A
Explanation: The children’s ages should be x, (x + 3), (x + 6), (x + 9) and (x + 12).Then 50 = x + (x + 3) + (x + 6) + (x + 9) + (x + 12).20 x 5,x equals 4.The youngest child’s age is x = 4 years.
3. A father told his son, “At the time of your birth, I was the same age as you are now.” If the father is currently 38 years old, the son was five years ago: a. 14 years b. 19 years c. 33 years d. 38 years
Answer: A
Explanation: Let’s say the son is currently x years old. As a result, (38 – x) Equals x.2 x 38 =x equals 19.5 years ago, son’s age was (19 – 5) = 14 years.
4. A is two years older than B, who is twice her age, and C is twice her age. What is B’s age if the sum of A, B, and C’s ages is 27? a. 7 b. 8 c. 9 d. 10
Answer: D
Explanation: Assume C is x years old. Then B’s age is equal to 2x years. A’s age is equal to (2x + 2) years.27 = (2x + 2) + 2x + 2x + x,5 x 25 =x equals 5.As a result, B’s age is 2x = 10 years.
5. Sameer and Anand are currently 5 and 4 years old, respectively. In three years, their ages will have shifted to 11:9, respectively. What is Anand’s current year of birth? a. 24 b. 27 c. 40 d.Cannot be determined
Answer: A
Explanation: Let Sameer and Anand’s current ages be 5x and 4x years, respectively.After that, 5x + 3/4x + 3 = 11/9.11(4x + 3) = 9(5x + 3).44x + 33 = 45x + 27.45x minus 44x equals 33 minus 27.x equals 6.Anand’s current age is 4x = 24.
6. His father is 24 years his senior. He will be double the age of his son in two years. His son is the following age: a. 14 years b. 18 years c. 20 years d. 22 years
Answer: D
Explanation: Let’s say the son is currently x years old. Then man’s current age is equal to (x + 24) years.2(x + 2) Equals (x + 24) + 2,2x + 4 Equals x + 26,x equals 22.
7. Six years ago, the age difference between Kunal and Sagar was 6:5. The ratio of their ages will be 11:10 in four years. What is Sagar’s current age? a. 16 years b. 18 years c. 20 years d. Cannot be determined
Answer: A
Explanation: Let Kunal and Sagar’s ages from 6 years ago be 6x and 5x years, respectively.As a result, (6x + 6) + 4/(5x + 6) + 4 = 11/10.10(6x + 10) equals 11(5x + 10)=5×10 x equals 2.(5x + 6) = 16 years is Sagar’s current
8. A father’s and his son’s current ages add up to 60 years. Six years ago, the father was five times the son’s age. Son’s age after 6 years will be: a. 12 years b. 14 years c. 18 years d. 20 years
Answer: D
Explanation: Let the son and father’s current ages be x and (60 -x) years, respectively.As a result, (60 – x) – 6 = 5 (x – 6),x = 5x – 30 = 54,84 = 6x,x equals 14.After 6 years, the age of the son is (x+ 6) = 20 years.
9. Currently, the age difference between Arun and Deepak is 4 to 3. Arun will be 26 years old in 6 years. Deepak’s current age is a. 12 years b. 15 years c. 19 and half d.21 years
Answer: B
Explanation: Let Arun and Deepak’s current ages be 4x and 3x years, respectively. Then,26 = 4x + 6 20 = 4x,x equals 5.Deepak’s age is 3 times his age, or 15 years.
10. Sachin is seven years younger than Rahul. What is Sachin’s age if their ages are in the ratio of 7 to 9? a. 16 years b. 18 years c. 28 years d. 24.5 years
Answer: D
Explanation: Let’s say Rahul is x years old.Sachin’s age is then (x – 7) years.7/9 = x − 7/x,7x = 9x – 63,63 = 2x,31.5 = x,Sachin’s age is thus =(x – 7) = 24.5 years.
11. The current ages of three people in the ratios of 4:7:9. Eight years ago, their combined ages were 56. Determine their current ages (in years). a. 8, 20, 28 b. 16, 28, 36 c. 20, 35, 45 d. 20, 35, 45
Answer: B
Explanation: Let’s say their current ages are 4x, 7x, and 9x years.As a result, (4x – 8) + (7x – 8) + (9x – 8) = 56.20 x 80 =x equals 4.They are 4x = 16 years old, 7x = 28 years old, and 9x = 36 years old, respectively.
12. When Ayesha was born, her father was 38 years old, and her mother was 36 years old when her four-year-younger brother was born. What’s the gap in age between her parents? a. 2 years b. 4 years c. 6 years d. 8 years
Answer: C
Explanation: When Ayesha’s brother was born, her mother was 36 years old.When Ayesha’s brother was born, her father was (38 + 4) years old, making him 42 years old.(42 – 36) years = 6 years is the required difference.
13. A person’s current age is two-fifths of his mother’s age. He will be half the age of his mother after 8 years. What is the mother’s current age? a. 32 years b. 36 years c. 40 years d. 48 years
Answer: C
Explanation: Let’s say the mother is currently x years old.The person’s current age is then 2/5 x years.1/2 (x + 8) = 2/5 x + 8,5(x + 8) = 2(2x + 40).x equals 40.
14. Q is the same age as R and the same age as T. What is the exact age difference between R and Q if the total of R and T’s ages is 50 years? a. 1 year b. 2 years c. 25 years d. Data inadequate
Answer: D
Explanation: 1. The age difference between R and Q equals the age difference between Q and T.2. The sum of R and T’s ages is 50, i.e. (R + T) = 50.R – Q =? is the question.,Q – T = R – Q.2Q = (R + T).As a result, (R + T) = 50.As a result, 50 = 2Q, and Q = 25.(R – Q) =? is the question.We know the value(age) of Q (25), but we have no idea how old R is.As a result, (R-Q) cannot be calculated.
15. Ten years ago, the father was three times the age of his kid. In ten years, the father will be double the age of his kid. Their current ages are distributed as follows: a. 5 : 2 b. 7 : 3 c. 9 : 2 d. 13 : 4
Answer: B
Explanation: Let’s say the father and kid were 3x and x years old 10 years ago.As a result, (3x + 10) + 10 = 2[(x + 10) + 10 .2x+40 = 3x + 20.x equals 20.The required ratio is (3x + 10):(x + 10) = 70:30 = 7:3.
16. How old is Sonia right now? I. Sonia’s current age is five times that of Deepak’s. II. Her age was twenty-five times that of Deepak five years ago. a. I alone sufficient while II alone not sufficient to answer b. II alone sufficient while I alone not sufficient to answer c. Either I or II alone sufficient to answer d. Both I and II are necessary to answer
Answer: D
Explanation: D = S/5 I. S = 5D I. S = 5D I. S = 5D I. S = 5D I. S (i)S – 5 = 25 (D – 5) S = 25D – 120 S = 25D – 120 (i)We get S = 25 x S/5 – 120 by using I in (ii)4S equals 120.S is equal to 30.As a result, I and II combined provide the solution. So, the proper response is (E).
17. The average age of a department’s personnel is 30 years. Ten employees will retire in the coming year. What will the average age be in a year’s time? I. The retirement age is 60. II. The department has a total of 50 workers. a. I alone sufficient while II alone not sufficient to answer b. II alone sufficient while I alone not sufficient to answer c. Either I or II alone sufficient to answer d. Both I and II are necessary to answer
Answer: D
Explanation: I. The retirement age is 60 years old.II. The department has a total of 50 workers.50 employees have an average age of 30 years.The total age of the 50 employees is 1500 years (50 x 30).The number of employees for the next year is set at 40.Next year’s total age of 40 employees is 940 (1500 + 40 – 60 x 10)Next year’s average age will be 940/40 years, or 23 1/2 years.As a result, the solution is given by combining I and II. So, the proper response is (E).
18. Divya is twice Shruti’s age. What is the age gap between them? I. In five years, the age difference between them will be 9:5. II. Ten years ago, their age ratio was 3 to 1. a. I alone sufficient while II alone not sufficient to answer b. II alone sufficient while I alone not sufficient to answer c. Either I or II alone sufficient to answer d. Both I and II are not sufficient to answer
Answer: C
Explanation: Let D be Divya’s current age, and S be Shruti’s current age.After that, D = 2 x S D – 2S = 0….I D + 5/S + 5 = 9/5…. (ii)D – 10/S – 10 = 3/1 D – 10/S – 10 = 3/1 D – 10/S – 10 = 3/1 D – (iii)We obtain 5D + 25 = 9S + 45 from (ii) and 5D – 9S = 20 from (ii) (iv)D – 10 = 3S – 30 D – 3S = -20 D – 10 = 3S – 30 D – 3S = -20 D – 10 = 3S – 30 D – 3S = -20 D – 10 = 3S – 30 D – (v)We may deduce the solution from I and (ii).We also obtain the solution from I and (iii). I, as well as II, provide the solution on our own. As a result, the right response is (C).
19. How old is Arun right now? I. When Arun was five years old, he was twice the age of his son. II. Arun and his kid are currently 11 and 6 years old, respectively. III. In five years, the age difference between Arun and his son would be 12:7. a. Only I and II b. Only II and III c. Only I and III d. Any two of the three
Answer: D
Explanation: II. Make Arun’s and his son’s current ages 11x and 6x years, respectively.I. Arun’s age was 2 times his son’s age 5 years ago.III. In 5 years, Arun will be 12 years old.7-year-old son.Any two of the aforementioned will clearly indicate Arun’s current age.The correct response is (D).
20. How old is Ravi right now? I. Ravi’s current age is half that of his father. II. Ravi’s age will be 6:11 when compared to his father’s age after 5 years. III. Ravi is a year and a half younger than his older brother. a. I and II only b. II and III only c. I and III only d. All I, II and III
Answer: A
Explanation: I. Assume Ravi is currently x years old. Then his father’s current age is equal to 2x years. II. Ravi’s age/age Father’s = 6/11 after 5 years. III. Ravi is the younger of the two brothers. We obtain x + 5/2x + 5 = 6/11 from I and II. This yields x, which is the solution. As a result, the solution is given by combining I and II. III is obviously superfluous.
21. What is Tanya’s age right now? I. Tanya and her brother Rahul are three and four years apart in age. II. In 5 years, the age difference between Tanya and Rahul will be 4 to 5. III. Rahul is five years Tanya’s senior. a. I and II only b. II and III only c. I and III only d. Any two of the three
Answer: D
Explanation: I. Make Tanya and Rahul’s current ages 3x and 4x years, respectively. II. (Tanya’s age) : (Rahul’s age) = 4 : 5 after 5 years. (Rahul’s age) + (Tanya’s age) = (Rahul’s age) + 5. We obtain 3x + 5/4x + 5 = 4/5 from I and II. This results in x. Tanya’s age = 3x has been discovered. As a result, I and II provide the solution. We obtain 4x = 3x + 5 from I and III. This results in x. Tanya’s age = 3x has been discovered. As a result, I and III provide the solution. From III: Assume Tanya is currently t years old. Rahul’s current age is then (t + 5) years. As a result of II and III, we get: t/t + 5 = 4/5. This returns thus, whereas II and III return the answer.
22. After 5 years, what will be the age difference between Sam and Albert? I. Sam’s current age is four years greater than Albert’s current age. II. Albert is currently 20 years old. III.
