Given:
The cost of a mobile phone is Rs. 3000.
A gain of 10% should be made after a discount of 20%.
To find:
The marked price of the mobile phone.
Solution:
Let's assume the marked price of the mobile phone to be 'x'.
Calculating the Selling Price (SP) after a discount of 20%:
Discount = 20% of x = (20/100) * x = 0.2x
Selling Price (SP) = x - Discount = x - 0.2x = 0.8x
Calculating the Cost Price (CP) after a gain of 10%:
Gain = 10% of 3000 = (10/100) * 3000 = 0.1 * 3000 = 300
Cost Price (CP) = 3000 - Gain = 3000 - 300 = 2700
Calculating the marked price (x) using the formula:
SP = CP + Gain
0.8x = 2700 + 300
0.8x = 3000
x = 3000 / 0.8
x = 3750
Therefore, the marked price of the mobile phone is Rs. 3750.

a) Rs. 4000 - Not the correct answer
b) Rs. 4125 - Not the correct answer
c) Rs. 4025 - Not the correct answer
d) Rs. 4100 - Not the correct answer
None of the given options match the calculated marked price of Rs. 3750.

Gain = 10% of 3000 = (10/100) * 3000 = 0.1 * 3000 = 300
Cost Price (CP) = 3000 - Gain = 3000 - 300 = 2700
Calculating the marked price (x) using the formula:
SP = CP + Gain
0.8x = 2700 + 300
0.8x = 3000
x = 3000 / 0.8
x = 3750
