On selling 250 cascades, a man had an equal gain to the selling price of 25 cascades. Find his gain percent
Jet001 [13]

Answer:

11.11%

Step-by-step explanation:

The selling price is 250

The cost price is 250-25

= 225

Therefore the gain can be calculated as follows

=250-225x/225x×100

1/9 ×100

= 0.1111×100

= 11.11%

Hence the gain is 11.11%
