Question

the age of a boy is 1.5 times of his age 10 years ago. what is his present age?​

Answer 1

Answer:

C) 12 years

Description for Correct answer:

boy's present age = x years

Amay's present age = 1.5 x years

After 4 years,

1.5x + 4 = 2 (x - 4)

=>1.5x + 4 = 2x - 8

=> 2x - 1.5x = 12 => 0.5 x = 12

=> x=120.5=12×105 = 12

Required difference = 1.5 x - x = 0.5x = 0.5 x 24 = 12 years
