Question

5. A trader marked his goods at 20% above the cost price. If he allows his
customer a 10% discount, find his profit per cent?(related to
financial arithmetic)

Answer 1

Answer:

Let CP = Rs 100

MP = Rs 120 [20% above CP]

Discount = 15%

ie = 15% of MP 

=10015×120=RS18

SP = MP- Discount 

=(120−18)rs

=Rs102

gain % =CPgain⇒100

=1002×100

=2 %
