Ratio of present age of A and B is 4 : 3. After 6 years the ratio of age of B and C will be 3 : 2. If the present age of C is 32 years, then after 3 years age of A will be:
Answer & explanation
Correct answer: option 4
Present age of C = 32
After 6 years C's age = 38
ATQ, after 6 years ratio⇒ B : C = 3 : 2
⇒ 2R = 38
⇒ 1R = 19
⇒ B's age after 6 years = 3R = 57
⇒ Present age of B = 57 - 6 = 51
Now,
Present age of A and B ⇒ 4R and 3R
⇒ 3R = 51
⇒ 1R = 17
⇒ A's present age = 4R = 68
⇒ After 3 years age of A = 68 + 3 = 71 years
