Question

raju's father is thrice as old as raju. after 12 years, his age will be twice that of his son. find their present ages.

Answer 1

let raju age be x
father's age be 3x
3x+12=2(X+12)
3x+12=2x+24
3x-2x=24-12
x =12
raju age = x= 12
father's age=3x=3×12=36

Answer 2

Step-by-step explanation:

$raju \: age \: = x \\ father \: age \: = \: 3x \\ 3x + 12 = 2( x+ 12) \\ 3x + 12 = 2x + 24 \\ 3x - 2x = 24 - 12 \\x = 12 \\ rajesh \: age= 12 \\ father \: age = 12 \times 3 = 24$
