Question

What is the formula to find the rate of discount when M.P and S.P after discount is given.

Answer 1

The discount is given in percentage. Hence, the M.P. is taken as Rs 100. Rate of discount = 5%. Amount of discount = (5/100)×100 = Rs 5.

Answer 2

Step-by-step explanation:

$s.p = \frac{100 \: - \: d\%}{100} \times m.p$

$\frac{s.p}{m.p} \times 100 = 100 - d\%$

$d\% = 100 - ( \frac{s.p}{m.p} \: \times 100)$
