Question

The ages of Arohi and Sneha are in the ratio 5:7. Four years later, their will be the ratio 3:4. Find Arohi's age​

Answer 1

Answer:

let present age of arohi be x

present age of sneha be y

from condition 1

x/y=5/7

x=5y/7......equation 1

from condition 2

x+4/y+4=3/4

4(x+4)=3(y+4)

4x+16=3y+12

16-12=3y-4x

4=3y-4x

from equation 1, substitute the x value

4=3y-4(5y/7)

4=3y- 20y/7

4=21y-20y/7

4=y/7

y=28.....equation 2

from equation 2,substitute the value of y in equation 1

x=5y/7

x=5×28/7

x=20

therefore, present age of arohi is 20yrs

present age of sneha is 28yrs
