Question

A shopkeeper marks his goods at 40% above the cost price but allows a discount of 5% for cash payment to his customers. What actual profit does he make, if he receives Rs 1064 after paying the discount?

Answer in Brief

Solution

\[\text { Let the original cost price of the item be Rs . x } . \]

\[\text { MP = x } + \frac{40x}{100} = 1 . 4x\]

\[\text { Discount = MP - SP }\]

\[MP - \frac{\text { Discount % } \times MP}{100} = SP\]

\[1 . 4x - \frac{5 \times 1 . 4x}{100} = 1064\]

\[\frac{1 . 4x \times 100 - 5 \times 1 . 4x}{100} = 1064\]

\[\text { So, x }\left( 1 . 4 \right)\left( 0 . 95 \right) = 1064\]

\[x = \frac{1064}{\left( 1 . 4 \times 0 . 95 \right)}\]

\[ = \frac{1064}{1 . 33}\]

\[ = Rs . 800\]

\[\text { Profit = Rs } . (1064 - 800)\]

\[ = \text { Rs }. 264\]

\[\text { Thus, the actual profit by the shopkeeper is Rs } . 264 . \]
