Question

The ratioof present ages of two girls is 3:5.Five years ago the ratio of their ages was 1:2 find their present ages.

Answer 1

Answer:

15 and 25

Step-by-step explanation:

let that ages of two girls are a and b

present ages a/b=3/5

a=3b/5

Five years ago (a-5)/(b-5)=1/2

2(a-5)=b-5

2*3b/5 -2*5=b-5

6b/5 - b =10-5

b/5 =5

b=25

then a=3*25/5=15
