Question

A dealer buys some pen from a wholesaler at the rate of rs 30 per pen and marked them at rs 40 each how much discount he shound allow to get a profit of 20%

Answer 1

Answer:

10 %

Step-by-step explanation:

CP of one pen = ₹30

Gain % = 20%

SP = ( 100+Profit% / 100 ) × CP

=(100 + 20%/100) × 30rs

= ₹36

Given,

MP of the pen = ₹40

and, SP of the pen = ₹36

=>Discount = ₹40 - ₹36

= ₹4

Now,

Discount % = Discount/Mp ×100

= 4/40 ×100%

= 10%

∴ He should allow a discount of 10% in order to gain 20%
