Question

shalin mother is three times the age of shalin After 5 years, the ratio of their ages will be 5:3 . find their present ages.
​

Answer 1

Answer:

let shalin's age be x

therefore her mother's age = 3x

after 5 years,

shalin's age = x + 5

her mother's age = 3x + 5

according to the question,

3x + 5 : x + 5 :: 5 : 3

(3x + 5) 3 = (x+5) 5

9x + 15 = 5x + 25

9x-5x = 25-15

4x = 10

x = 10/4

x = 2.5

so,

shalin's age = x = 2.5 years

her mother's age = 3x = 7.5 years
