Question

the s.p. of four fans is same as the c.p of 5 fans. Find the gain per cent

Answer 1

hello mate

here is your solution

It is given that

s.p. of 1 fan =1 rs

then total cp

if cp of 1 fan =1 rs

then total
cp =>
5rs= sp of 4 fans

so sp of 1 fan= 5/4 rs

so profit per fan = 5/4-1 =1/4

gain%=profit/cp *100

=1/4/1 *100

=25% =5rs= sp of 4 fans

so sp of 1 fan= 5/4 rs

so profit per fan = 5/4-1 =1/4

gain%=profit/cp *100

=1/4/1 *100

=25%

hence benefit is of 25%.

I hope helps you
