Answer 1

Hii Mate here is your Answer,

Given the age of Mother and Daughter is in Ratio 3:1

》 Let Mother's age be 3x
Let Daughter's age be x

After 5 years
Mother Age will be 3x+5
Daughter Age will be x+5

According The question after five years their ratio is 5:2 = 5/2 .... 5 by 2

So we frame an equation from these data

i.e. (3x+5) / (x+5) = 5/2

》 2(3×+5) = 5 (x+5) ........Cross multiply

》 6x + 10 = 5x + 25 ..... Solving Brackets

》 6x-5x = 25-10

》 x = 15


Hence x = 15

Daugter's Age = x = 15
Mother's Age = 3x = 45
