Question

the ratio of ages of 3 person A B C is 6 years back was 5:6:7 , find the present age of each if the summation of their present ages is 135 years?​

Answer 1

Answer:

Let x be the ratio. Then-->

A's present age=5x+6

B's present age=6x+6

C's present age=7x+6

Since sum of their present ages is 135-->

5x+6+6x+6+7x+6=135

18x+18=135

18x=113

x=113/18
