Question

A trader marks his goods at 30% above cost price and allows a discount of 10%. What is his gain per cent?

Answer 1

Let CP will be Rs.100 

Marked Price = Rs.130 

10% Discount on Marked Price = 10% of Rs.130 

= Rs.13 

So, SP = 130 -13 

= Rs.117 

Gain = SP – CP 

= 117 – 100 

= Rs.17

\(Gain\%=\frac{Gain\,\times\,100}{CP}\)

= (17 × 100) / 100 

= 17%
