​

Answer 1

Step-by-step explanation:

present ages of vatsala and Sara 14 yes and 10 yrs yes respectively

ratio should become=5:4

let the years after which this ratio would be possible be X.

so,

(14 + X) / (10 + X) = 5/4

4 (14+ X) = 5 ( 10 + X)

56 + 4x= 50 + 5x

= X= 6

so, after 6 years the ratio of their ages will become 5:4

or

14 + :10 + X= 5:4

by cross multiplication 4(14+X)= 5(10+X)

56+4x=50+5x

6=5x4x

X=6

after 6 years ratio of their age will be become 5:4
