Answer 2

Step-by-step explanation:

The dealer of electronic goods allows 12% discount

For a Market Price of ₹100, the selling price is ₹(100 - 12) = ₹88

Still he makes a profit of 10%

For a cost price of ₹100, the selling price is ₹(100 + 10) = ₹110

In other words, When the selling price is ₹110, the cost price is ₹100

∴ When the selling price is ₹88, the cost price is ₹88 . \frac{100}{110}88.

110

100

= ₹80

And he gains ₹(88 - 80) = ₹8

Now He gains ₹8, when the Market Price is ₹100

∴ He gains ₹120, when the Market Price is ₹120 . \frac{100}{8}120.

8

100

=₹1,500
