1. Six years from now the combined age of father and son will be 54. If currently son is 5 times younger than his father then what is the present age of the father?
- A. 30
- B. 30
- C. 30
- D. 30
Answer: Option C
Explanation:
Let the present age of son and his father be S and 5S respectively. Six years from now, their ages will be (S + 6) and (5S + 6) respectively.
So, S + 6 + 5S + 6 = 54
or, 6S + 12 = 54
or, 6S = 54 - 12
or, 6S = 42
or, S = 42/6 = 7
So, present age of the father = 5 × 7 = 35 years
