Flourescene of minerals short point​

Answer 1

Explanation:

SP of computer = Rs.24480

Loss = 4%

CP =\frac{SP \times 100}{100-L\%}CP=

100−L%

SP×100

CP =\frac{24480 \times 100}{100-4}CP=

100−4

24480×100

CP =25500CP=25500

Now we are supposed to find the selling price at which the gain is 4%

So, CP = Rs. 25500

Profit% = 4%

Profit = 4\% \times 255004%×25500

Profit = \frac{4}{100}\times 25500

100

×25500

Profit = 10201020

SP = CP+Profit = 25500+1020=Rs.26520

Hence he should sell it at Rs.26520 to gain 4%
