Question

By what percent above the cost price should a dealer mark a pen so that after allowing a discount of 4 percent he gains 20 percent

Answer 1

Let the CP be 100₹ and MP be rs X.

So the gain % after a discount=12%.

So gain =12% of 100 = rs 12.

So, SP of the article= CP+Gain = RS (100+12)= 112.

Discount% is 20% so discount= 20% of marked price that is RS 20/200*x = RS 20 x/100 =RS x/5.

As per the question, marked price-discount = SP.

So x-x/5=112 so x=RS 140 .

Amount marked above the cp=mp-cp =rs40.

Amount increased/cp*100=40*100/100=40.
