Sum of the present ages of J, P and S is 80 years. 10 years ago from the present the ratio of ages of J, P and S was 3 : 5 : 2. What is the present age of P?
Show answer & explanation
Correct answer: A
Explanation
10 years ago ages = 3x, 5x, 2x
Present ages = (3x+10), (5x+10), (2x+10)
Sum: 10x + 30 = 80 ⇒ 10x = 50 ⇒ x = 5
Age of P = 5x + 10 = 25 + 10 = 35 years
Correct Answer: 35 years
