Question

The difference between the ages of Two Sisters is 10 years. 15 years ago their ages are in the ratio 2:1 find the ratio of their ages 15 year hence

Answer 1

Answer:

first sister age = x+ 10

second sister age = x

difference between their ages= 10

15 years ago ages of girl = 2:1

A.T.Q.

x+10+x=((2x)+ x)+15

2x+10=3x+30

2x+3x=10+30

5x=40

x=40/5

x=8

first sister age after 15 years ago = 2X8= 16

second sister age after 15 years ago =15
