Question

A trader marks his goods $40$% above the cost price. He sells them at a discount of $5$%. What is his loss or gain percentage?

Answer 1

$MP=140\%\times CP$

discount$=5\%$

$SP=95\%\times 140\%CP⟹SP=1.33\times CP⟹SP/CP=1.33$

Gain$\%$$=\frac{SP-CP}{CP}\times 100⟹(1.33-1)\times 100=33\%$

Hence, gain$=33\%$
