Question

Find the selling price when c.p=56.25, gain=20%

Answer 1

sp=cp×100+profit%÷100
=56.25×100+20÷100
=11.25×6÷5
=67.5

Answer 2

Hence  the selling price is 67.5 units.

Step-by-step explanation:

Given:

Here, C.P. = 56.25, profit percent = 20%

Selling price = (100 + profit%) $\frac{C.P.}{100}$

                      = $100+20\times \frac{56.25}{100}$

                      = $120\times \frac{56.25}{100}$

                      = $6 \times \frac{56.25}{5}$

                      = $\frac{337.5}{5}$

                      = 67.5

Hence  the selling price is 67.5 units.
