Question

the present ages of parul and kajol are in the ratio of 15:8. After 10 years the ratio of their ages will be 5:3. find their present ages​

Answer 1

Answer:

Step-by-step explanation:

let their ages at present be 15 m and 8 m

After ten years their ages would be 15 m + 10 and 8 m + 10

Given in the problem that (15m + 10) / (8 m + 10) = 5/3

Cross mulitplying we get 45 m + 30 = 40 m + 50

===> 45 m - 40 m = 50 - 30 = 20

Or 5 m = 20

Thus m = 4

Hence their present ages are 60 and 32
