Question

The marked price of a book is rs 360. The shopkeeper sold it for rs 300. How much percent discount did shopkeeper give? *​

Answer 1

$\sf \: Marked \: price (M.P) = Rs. 360 \\ \sf \: Selling \: price (S.P) = Rs. 300 \\ \sf \: Discount = M.P - S.P \\ \sf \implies \: Rs. 360 - Rs. 300 \\ \sf \implies \: Rs. 60$

$\boxed{ \underline{ \gray{\sf \: Discount \% = \dfrac{Discount}{M.P} \times 100}}}$

$\sf \: Discount \%= \dfrac{ \cancel6 \cancel0}{ \cancel{36} \cancel0 \: ^{3} } \times \cancel{100} \: ^{50} \\ \\ \sf \implies \: \frac{50}{3} \\ \\ \boxed{ \red{\sf \implies \: 16.7\%}}$
