Correct Answer: 39 years
Explanation:
Let the present ages of B and A be x years and (x + 9) years respectively.
Then, (x + 9 + 10) = 2(x - 10)
? x = 39
Correct Answer: 36 years
Explanation:
Let Ramesh's present age be x years. Then Shyam's present age = 3x years.
? 2(x + 12) = (3x + 12)
? x = 12
Hence, Shyam's present age is 36 years.
Correct Answer: 36 years, 9 years
Explanation:
Let the present age of the father and son be x years and (45 - x)years respectively.
Then, (x - 5)(45 - x - 5) = 4(x - 5)
? -x2 + 41x - 180 = 0
? (x - 5)(x - 36) = 0
? x = 36
? The present ages of father and son are 36 years and 9 years respectively.
Correct Answer: 32 years
Explanation:
Let the son's be x years, then father's age = 4x years
? (4x - 5) = 9(x - 5)

? x = 8
? Present age of the man = 32 years
Correct Answer: 41 years

Correct Answer: 35 years
Explanation:
Let A's age 10 years ago = x years
Then, B's age 10 years ago = 2x years
? (x + 10) / (2x + 10) = 3 / 4
? 4(x + 10) = 3(2x + 10)
? x(6 - 4) = 40 - 30
? x = 5
&ther4; Total of their present ages = (x + 10) + (2x + 10)
= (3x + 20)
= 35 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:
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
