Find the cost price if the selling price is rupees 12 and gain is 20%​

Answer»

Answer:

The cost price is Rs. 10.

Step-by-step explanation:

The formula to COMPUTE the selling price in CASE of GAIN is:

SP=CP[1+\frac{Gain}{100} ]

Given:

SP = Rs. 12

Gain = 20%

Compute the VALUE of CP as follows:

SP=CP[1+\frac{Gain}{100} ]\\12=CP[1+\frac{20}{100} ]\\12=CP\times 1.20\\Cp=\frac{12}{1.20}\\ =10

Thus, the cost price is Rs. 10.
