Question

Ram is three times as old as his Sam. 2 years ago he was five times as old as Sam. What is the present age of Ram

Answer 1

Let Sam's age be $x$ years old and Ram is three times as old as sam is $3x$.

Two years ago Ram is five times as old as sam.

$5(x-2)=3x-2\\5x-10=3x-2\\2x=8\\x=\frac{8}{2}\\x=4$

Ram present age is $=3 \times 4$

Ram present age is 12 years old.
