The ratio of the ages of Bala and Babu is 13: 11. The total of their ages is 3.6decades. The proportion of their ages after 0.95decades will be [1 Decade = 10 years] a) 24:23 b) 12:11 c) 27:24 d) 29:26

1 Answer

Answer :

D

A = 1.5

Bala’s age = 19.5years

and Babu’s age = 16.5 years

Proportion of their ages after 9.5 is = (19.5+9.5) : (16.5 + 9.5)

= 29 : 26
