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.
Step-by-step explanation:
[tex]s.p = \frac{100 \: – \: d\%}{100} \times m.p[/tex]
[tex] \frac{s.p}{m.p} \times 100 = 100 – d\%[/tex]
[tex]d\% = 100 – ( \frac{s.p}{m.p} \: \times 100)[/tex]
