Answer 2

The selling price is Rs.9100.

Step-by-step explanation:

Given : By selling an old refrigerator for rupees 7150, a man loses 12%.

To find : For how much should it be sold to gain 12%?

Solution :

The selling price is Rs.7150.

Loss%=12 %

The cost price is $CP=\frac{100}{100-L\%}\times SP$

$CP=\frac{100}{100-12}\times 7150$

$CP=\frac{100}{88}\times 7150$

$CP=8125$

So, the cost price is Rs.8125.

The gain% is 12%.

The selling price is given by, $SP=\frac{100+P\%}{100}\times CP$

$SP=\frac{100+12}{100}\times 8125$

$SP=\frac{112}{100}\times 8125$

$SP=9100$

The selling price is Rs.9100.
