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 x 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.
