The average age of a man and his son is 55 years. The ratio of their ages is 7 : 4, respectively. What will be the ratio of their ages after 6 years?
Answer & explanation
Correct answer: option 4
ATQ,
Lets assume, present age of man is 7x and son is 4x
Sum of ages of father and son = 55 x 2 = 110
Given, 7x + 4x = 110
⇒ x = 10
After 6 years, father's age = 76
son's age = 46
Ratio of their ages after 6 years = 38:23
