Question

Find the selling price if cost price is Rs 20 and gain is 20%?​

Answer 1

Step-by-step explanation:

sp=20+20/20

sp=20+4=24

Answer 2

Given:

Cost price (C.P) = Rs. 20

Gain percentage = 20%

To find:

Selling price = ?

Formula to be used:

Gain % = $\[\frac{S.P-C.P}{C.P}\times 100\]$

Solution:

Step 1 of 1

• The values for C.P and gain percentage are given.
• When we substitute these values in gain percentage formula, we get the selling price.

Gain % = $\[\frac{S.P-C.P}{C.P}\times 100\]$

Let the S.P be 'X'

$20 = \[\frac{X-20}{20}\times 100\]$

Take the term with 'X' to L.H.S,

$X-20 = \[\frac{20\times 20}{100}\]$

$X-20=\[\frac{400}{100}\]$

$X-20=4\\\\ X=4+20\\\\ X=24$

Final answer:

The selling price is found as Rs.24.
