✺ Given :

• After 20 years the age of smita will be 4 less than 5 times of her present age.

✺ To FiNd :

• find the present age of smita ?

✺ Explanation :

Let , the present age of Smita is = X years

Hence , the age of Smita will be after 20 years

= (X+20) years.

Now , according to the Question ,

After 20 years the age of smita will be 4 less than 5 times of her present age ;

$\implies (X+20)=(5\times X-4)$

$\implies X+20=5X-4$

$\implies 20+4=5X-X$

$\implies 24=4X$

$\implies X=\dfrac{\cancel{24}}{\cancel4}$

$\implies\boxed{ X=6}$

✺ Therefore :

present age of smita is = 6 years.
