Question

The average age of a man and his twin sons is 36 years and ratio of his age to his sons age is 2:1:1. Find age of his sons.​

Answer 1

Step-by-step explanation:

According to the question, average age of man and his twin sons = 30

Total age = 30 x 3 = 90 yr

According to the question, Ratio of father and one son = 5 : 2

Ratio of father and both the sons = 5 : 2 : 2(As sons are born on the same day)

5x + 2x +2x = 90 or 9x = 90

X = 10

Age of father = 5 X 10 = 50 yr.

Answer 2

Answer:

27

Step-by-step explanation:

Let 2x be the age of the man and x be the age of his sons.

(2x+x+x)/3 = 36

x = 27
