Correct Answer: 10 years
Explanation:
Let the ages of A and B be 2x and 3x years respectively.
From question, (2x + 5) / (3x + 5) = 3 / 4
? 4(2x + 5) = 3(3x + 5)
? x = 5
&ther4; A's present age = 2x = 10 years
Correct Answer: 24 years
Explanation:
Let the current ages of A and B be 2x and 5x respectively
Now from question (2x + 8) / (5x + 8) = 1 / 2
? 2(2x + 8) = (5x + 8)
? x = 8
? Difference of their ages = (5x - 2x) = 3x = 24 years
Correct Answer: 16 years
Explanation:
Let their ages one years ago be 4x and 3x years.
? (4x + 2)/(3x + 2) = 5 / 4
? 4(4x + 2) = 5(3x + 2)
? x = 2
? Sum of their present ages = (4x + 1) + (3x + 1) = 16 years
Correct Answer: 24 years
Explanation:
Sum of age of A and B, 3 years ago = (18 x 2) = 36 years
Sum of ages of A, B and C, now = (22 x 3) = 66 years
Sum of ages of A and B, now = (36 + 6) years = 42 years
? C's present age = (66 - 42) years = 24 years
Correct Answer: 24 years
Explanation:
Let Anil's age = x years
Then, Prashant's age = (48 - x) years
Let the age of Jayesh be P years.

? 2p = 48
? p = 24
Correct Answer: 11 : 3
Explanation:
Let son's age 1 year ago be x years.
? Father's age 1 year ago = 4x years
? 4x + 7 = 2(x + 7) + 9
? 2x = 23 - 7
? x = 8
Ratio of father's and son's present ages = (4x + 1) : (x + 1) = 33 : 9 = 11 : 3
Correct Answer: 7 : 3
