▪$x + \frac{1}{5} x = 21$

▪$\frac{5x + x}{5} = 21$

▪$\frac{6x}{5} = 21$

▪$x = 21 \times \frac{5}{6}$

▪$x = \frac{35}{2}$

▪$x = 17.5$

Answer 2

Answer:

The required quantity is 17.5 .

Step-by-step explanation:

Let the quantity be x.

Its one fifth part is x/5.

Given that a quantity and its fifth part added together became 21. So,

x + $\frac{x}{5}$ = 21.

⇒$\frac{5x + x}{5}$ = 21

⇒$\frac{6x}{5}$ = 21

⇒ x = $\frac{21 X 5}{6}$ = 17.5.

So, the required quantity is 17.5.

Verification : 17.5 + 17.5/5 = 17.5 + 3.5 = 21.
