Answer 1

Question :

in 12 years a man will be twice old as he was 12 years ago .find his present age

Answer :

• Let the man's present age be x

• his age 12 years before = x - 12

• after 12 years he will be twice old as he was before 12 years = 2( x - 12 ) = x + 12

$\longrightarrow\sf{ 2x - 24 = x + 12}$

$\longrightarrow\sf{ 2x - x = 12 + 24}$

$\longrightarrow\sf{ x = 36}$

Therefore his present age is 36 .
