Solution
Let us say the cost price of an item is X
It is said that it is marked to make a profit of 20%.
That means it is marked at 1.2X
Ravi gets a 10% discount on the marked price,
$$0.9\left(1.2X\right)=1.08X$$
Saves 15 rupees, so 1.2X-1.08X
0.12X=15
X=125
Profit made by Gopi is 0.08(125)=10 rupees.
