Question

Four year hence a boy will be twice as old as he was 6 years ago . What is his present age?

Answer 1

Answer:

his present age is 16

Step-by-step explanation:

let the boy's age be x

then 4 years hence his age would be (x+4)

and 6 years ago it would have been (x-6)

then as per given data,

x+4 = 2(x-6)

x+4 = 2x-12

x-2x = -12-4

-x = -16

therefore x = 16
