Question

A is 5 years older than b, b is 10 years older than

c. if the total age of a, b and c are 40. then how old is b?

Answer 1

Let,
Age of c = c
Age of b = (c+10) years
Age of A = (c+10+5) years


Sum of ages = 40

c +c+10+c+15=40

3c = 40-25

3c = 15

c =15/3=5

Age of c =5 years
Age of b = 5+10=15 years
Age of c = 5+15=20 years
