Question 77

After 25 years, Rama will be 5 times as old as he is now. Find his present age.

Answer 1

Let Rama's present age be x years.
Then, Rama's age after 25 years = (x + 25) years.
It is given that after 25 yr, Rama's age will be 5 times his present age.
Therefore, the equation is
$x+25=5x\Rightarrow 25=5x-x\left[transposingxtoRHS\right]\Rightarrow 25=4x\Rightarrow \frac{25}{4}=\frac{4x}{4}\left[dividingbothsidesby4\right]\Rightarrow 6\frac{1}{4}=x$
Hence, the present age of Rama's is $6\frac{1}{4}years.$
