Question

A mother is 30 years older than her son . In 12 years , she will be three times as

old as her son . Find their present ages .​

Answer 1

Answer:

present age of son = 3years

present age of son = 3yearspresent age of mother = 33years

Step-by-step explanation:

let present age of son be x

mother age = 30+x

after 12 years

(30+x + 12) = 3(x+12)

= 42+x = 3x + 36

=> 3x - x = 42-36

=> 2x = 6

=> x = 6/2

=> x = 3

30+x = 30+3 = 33

present age of son = 3years

present age of mother = 33years
