Question

on selling a calculator for rupees 1325 a man gained 6% for how much should he sell it to gain 12%

Answer 1

apply the formula then multiplly into two

Answer 2

Let the CP be x
$x \times \frac{100 + 6}{100} = 1325 \\ \frac{106}{100} x = 1325 \\ x = 1250$
In order to gain 12%
$= 1250 \times \frac{(100 + 12)}{100} \\ = 1250 \times \frac{112}{100} \\ = 1400$
