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
