Question

A mobile set is sold for rupees 4200 after a discount of 15% find the market price

Answer 1

Answer:

If the selling price of a mobile set was Rs 4200 and it was sold at a discount of 15 percent, then the market price is 4941.17 rupees

Step-by-step explanation:

Given

Selling price = 4200 rupees

Discount percentage = 15 percent

Discount = market price ( MP)- selling price

Discount percentage =[ discount / Market price (MP) ] *100

That is,

$15= \frac{MP-4200}{MP} *100\\\\\frac{15}{100} MP = MP-4200\\\\MP-\frac{3}{20} MP = 4200\\\\\frac{17MP}{20} = 4200\\\\17MP = 4200*20\\\\MP =\frac{84000}{17} \\\\MP =4941.17$

So the market price is Rs 4941.17
