Question

A dealer of scientific instruments allows 20% discounts on the marked price of the instrument and still makes a profit of 25%. If his gain over the sale of an instrument is Rs150, find the marked price of the instrument.

Answer 1

marked price will be Rs.750

Answer 2

Profit= 25%
Gain= Rs 150
Gain = Profit
Let the price after discount be x.
25/100×x=150
x= Rs 600
Discount= 20%
Therefore, (20% of 600)+600
=(20/100×600)+600
=120+600
=720.
Therefore, Marked Price = Rs 720.
