$$\frac{2}{5}$$ of x is $$8$$

=> $$\frac{2}{5} * x$$ = 8

=> x = $$8 * \frac{5}{2}$$ = $$\frac{40}{2}$$ = 20

=> $$\frac{1}{4} * x$$ = $$\frac{1}{4} * 20$$ = 5

Hence option D

(2/5)x = 8

x = 8(5/2)

x = 20

So 1/4 of 20 is 5.

$$\frac{2x}{5}$$ = $$8$$

So, $$x = 20$$

Now, $$\frac{x}{4}$$ = $$\frac{20}{4} = 5$$, Answer must be (D)
