Question

On selling a calculator for 1325, a man gains 6%. For how much should he sell it to
gain 12%?​

Answer 1

Answer:

1400

Step-by-step explanation:

SP of calculator = ₹1325

gain = 6%

$cp = \frac{sp \times 100}{100 + profit \%} \\ = \frac{1325 \times 100}{100 + 6 } = \\ = \frac{132500}{106} = 1250$

CP of calculator = ₹1250

gain = 12%

$sp = \frac{cp (100 + profit\%)}{100} \\ = \frac{1250(100 + 12)}{100} \\ = \frac{1250 \times 112}{100} = 1400$

Thus, SP of calculator = ₹1400
