Question

Ratio of present ages of two sister Rita and sita is 5:4,6years ago, ratio of their ages was 3:2. Find their present ages ​

Answer 1

As the ratio of their present ages is 3 : 4 ,

let their present ages be 3X and 4X.

So, 5 years ago, as the ratio of their ages was 5 : 7,

we can write (3x-5) : (4x-5) = 5 : 7.

Solving, we get X = 10.

Hence, their present ages are 3X = 30 and 4X = 40.

hope it helps you mate.

Answer 2

Step-by-step explanation:

let the ratio of their ages be 5 x and 4x

6 years ago...

5x-6/4x-6 = 3/2.....

cross multiplying.......

10x-12=12x-18......

2x=6.

x=3.........

Rita age = 5×3=15

sita age = 4×3=12
