Question

the ratio in the ages of A b and c six year before was 2:3:5.if the sum of their persent ages is 168 find their ages​

Answer 1

answer-

let the ratio of their ages 6 years ago in terms of x be-

2x:3x:5x

so their ages 6 years ago were

2x

3x

and, 5x

their present ages will be

2x+6

3x+6

5x+6

the sum of their present ages is

2x+6+3x+6+5x+6

A2Q, 2x+6+3x+6+5x+6= 168

10x + 18 = 168

10x= 168-18

10x= 150

x= 150/10

x=15

so their present ages are-

2*15+6 = 36

3*15+6= 51

and, 5*15+6= 81

hope it helps

have a nice day
