Question

The ratio of rita age to the age of her mother is 3:11 .the difference of their age is 24 .what will be the ratio of their age after 3 year

Answer 1

Answer:

1 : 3

Step-by-step explanation:

Let  Rita's age = A

Mothers Age = 24 + A

Given

A / (24+A) = 3/11

11A = 3(24 + A)

11A = 72 + 3A

11A - 3A = 72

8A = 72

Therefore A = 72 / 8 = 9

Ie Rita's Age = 9

Mothers Age = 24 + 9 = 33

Ratio of their ages after 3 yrs

9+3/33+3 = 12/36 = 1/3 = 1:3
