Answer 1

hope this helps uuu..........

Answer 2

Let Kartik's present age be x years.

So Raju's present age is x + 4 years.

Next year ,

Kartik's age = x + 1 years

Raju's age = x + 4 + 1 = x + 5 years

Next year Raju will be 2 times as old as kartik

So we have

x + 5 = 2 ( x + 1 )

$x + 5 = 2x + 2$

$5 - 2 = 2x - x$

$3 = x$

Thus Raju's present age = x + 4 = 7 years

And Kartik's present age = x = 3 years
