Question

The present age of Father is 45 years. The ratio of Father's age to son's age is 3:1. Find the present age of the son.​

Answer 1

Answer:

2:1 is the answer

Step-by-step explanation:

Present age of father = 45 years Present age of son = 15 years (i) Required ratio = 45/15 = 3/1 = 3 : 1 (ii) 5 years ago (when son was 10 years old) age of father = 45 – 5 = 40 years and age of son = 15 – 5 = 10 years Required ratio = 40/10 = 4/1 = 4 : 1 (iii) After 5 years, age of father = 45 + 5 = 50 years and, age of son = 15 + 5 = 20 years Required ratio = 50/20 = 5/2 = 5 : 2 (iv) when father will be 60 years old (i.e. after 15 years) age of son = 15 + 15 = 30 years Required ratio = 60/30 = 2/1 = 2 : 1
