Question

Sum of the present ages of Manish and savita is 31. Manish age 3 year ago was 4 time the age of savita find their present age's?

Answer 1

Answer:

Manish's age ≈ 6 years

Savita's age ≈ 25 years

Step-by-step explanation:

let Manish's age = x

savita's age = y

x + y = 31

Manish's age before three years = x - 3

According to the question ,

x - 3 = 4y

∴ x - 4y = 3

- 4y = - x + 3

y = - x +3 / 4

it is given that x + y = 31

∴ x + (x + 3 / 4) = 31

(4x + x + 3 ) / 4 = 31

5x + 3 = 31

5x = 31 - 3 =28

x = 28/5 ≈ 6

31 - x = y

31 - 6 = y = 25
