A is $25$ % older than $B$ , by what percent is $B$ younger than $A$ ?

Let the age of B = X yrs
Now, age of A = X + 25% of X
$= X + (25 / 100) \times X = X + (X = 4) = (\frac{5 X}{4})$ yrs
Now, B is $((\frac{5 x}{4}) - X)$ i. e. ( $\frac{x}{4}$ ) yrs younger than A
Now, in terms of percentage, [ (( $\frac{x}{4}$ )/ $(\frac{5 x}{4})$ )× 100]\% = 20 %

A is 25% older than B, by what percent is B younger than A ?

Let the age of B = X yrs Now, age of A = X + 25% of X =X+(25/100)×X=X+(X=4)=(5X4) yrs Now, B is ((5x4)−X) i. e. (x4) yrs younger than ANow, in terms of percentage, [ ((x4)/(5x4))× 100]\% = 20 %
