Question

some toffees are bought at 6 for a rupee and same number at 4 for a rupee if the whole lot is sold at 5 for a rupee find the gain or loss %​

Answer 1

Answer:

let,total no. of toffes be x

then,

total c.p = (x/2)*1/4 + (x/2)*1/6 --> 5x/24

total s.p = (x)*1/5 --> x/5

therfore loss = total c.p - total s.p= 5x/24 - x/5 = x/120

loss% = {(x/120)/(5x/24)}*100 = 4%
