Question

after 15 years the age of ashwin will be trible that of his age 15 years ago what is his present age

Answer 1

Let the present age of Ashwin be x years

His age after 15 years = (x + 15) years

His age 15 years ago = (x - 15) years

According to Quetion,

(x + 15) = 3(x - 15)

=> x + 15 = 3x - 45

=> x - 3x = - 45 - 15

=> - 2x = - 60

=> 2x = 60

=> x = 60 / 2

=> x = 30

Hence, the present age of Ashwin is 30 years

Answer 2

let ashwin's present age be x yrs.

his age 15 yrs ago = (x-15) yrs

hi age after 15 yrs = (x+15) yrs

3(x-15) = x + 15

3x - 45 = x + 15

2x = 60

x = 30
