Question

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

Answer 1

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.

Answer 2

Answer:

S.P. = Rs 12

Gain % = 20

so,

C.P. = SP/(100+Gain %)×100

= Rs 12 / (100 +20) × 100

= Rs 12 / 120 × 100

= Rs 10 ans.
