Answer 2

Answer:

for 1st fan C.P.=( 100/100+profit )×S.P.

=C.P.=(100/100+14)×1140=1000

C.P. for 1st fan =1000

C.P. for 2nd fan =(100/100-loss)×S.P.

C.P.=(100/100-5)×1140=1200

total C.P.=1000+1200=2200

total S.P.=1140+1140=2280

S.P.is greater than C.P. so there will be profit

profit =S.P.-C.P.=2280-2200=80

profit or gain percent=profit×100/C.P.

=80×100/2200=3.63 percent gain.
