Let the present age of Rita=x and her mother=y years, then
Ratio of their age = x/y=3/8 => 8x - 3y = 0 ---(i)
Difference of their age = y - x = 35 ---(ii)
Solving equation (i) & (ii), we get x=21, y=56
So, ratio of their ages after 4 years = (x+4)/(y+4) = (21+4)/(56+4) = 25/60 = 5/12

Let Rita’s age be 3x

Let her mother’s age be 8x

Difference in ages = 35

8x-3x=35

5x=35

x=7

Rita’s age is 21 years

Her mother’s age is 56 years

After 4 years

Her age is 25

Her mother’s age is 60

The ratio of her age to her mother’s age after 4 years will be
