प्रश्न

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

योग

उत्तर

Let Rama's present age be x yr

Then, Rama's age after 25 yr = (x + 25) yr

It is given that after 25 yr, Rama's age will be 5 times his present age

Therefore, the equation is x + 25 = 5x

⇒ 25 = 5x – x  ......[Transposing to RHS]

⇒ 25 = 4x

⇒ `25/4 = (4x)/4`  ......[Dividing both sides by 4]

⇒ `6 1/4` = x

Hence, the present age of Rama is `6 1/4` yr.
