Selling Price = Rs 2640


Find the percentage of the selling price:

100 + 10 = 110%


Find the cost price:

110% = 2640

1% = 2640 ÷ 110 = Rs 24

100% = 24 x 100 = Rs 2400


Find the new Selling Price:

15% gain = 0.15 x 2400 = Rs 360

New Selling Price = 2400 + 360 = Rs 2760


Answer: The cost price is Rs 2400 and the new selling price is Rs 2760

\huge\textbf{Solution}
<b>
Given

☞1st case

SP of the article= RS.2640

Gain= 10%

CP = \frac{SP \times 100}{100 + gain\%} \\

 = Rs( \frac{2640 \times 100}{100 + 10} ) \\ \\ = Rs( \frac{264000}{110}) \\ \\ = Rs \: 2400

➠So CP = Rs.2400

☞2nd case

Gain = 15%

SP = \frac{CP (100 + gain\%)}{100} \\ \\ = Rs \frac{2400(100 + 15)}{100} \\ \\ = Rs( \frac{2400 \times 115}{100} )\\ \\ = Rs \: 2760

➠New SP= 2760

✪Thank you✪

Have a colossal day ahead
