Question

Philoid · Accepted Answer

CP of first fan = Rs.1140

SP of first fan=

= Rs.1299.60

CP of second fan = Rs.1140

SP of second fan =

= Rs.1083

CP of both fans = 1140 + 1140

= Rs.2280

SP of both fans = 1299.60 + 1083

= Rs.2382.60

It is a case of Gain because SP is more than CP.

Gain = SP – CP

=2382.60 - 2280

= Rs102.60

= (102.60 × 100) / 2280

= 4.5%
