please tell me the answer very fastly with step by step explanation​

Answer 1

Answer:

2%

Step-by-step explanation:

Let CP be cost price

MP be market price

SP be selling price

Then

Let CP = Rs 100

MP = Rs 120 [20% above CP]

Discount = 15%

ie = 15% of MP 

=(15/100)×120=Rs. 18

SP = MP- Discount 

=(120−18)rs

=Rs102

gain % =CPgain⇒100

=(2/100)×100

=2 %
