Question

the ratio of the ages of two sisters is 2:3. six years later, the ratio of their ages will be 3:4. find their present ages

Answer 1

2:3:4 is my answer of this question

Answer 2

ratio of present age is 2:3
let common multiple is x
1st sister age=2x
another sister age =3x
six years later
age of 1st sister is 2x+6
age of another sister is 3x+6
so,
(2x+6)/(3x+6)=3/4
(2x+6)×4=(3x+6)×3
8x+24=9x+18
24-18=9x-8x
6=x
so present1st sister age=2x=12 years
presents another sister age =3x =18 years
