Question

the selling price of 10 tofees iss equal to the cost of 15 toffess.find gain or loss percent​

Answer 1

Answer:

Profit = 50%

Step-by-step explanation:

SP of 10 toffees = CP of 15 toffees

SP of 1 toffee = CP of 1.5 toffees

=> SP = 1.5*CP ...........(Eqn 1)

As SP is more than CP, there is profit.

Profit = SP - CP

         = 1.5*CP - CP

         = 0.5*CP

Profit% = 100*(Profit/CP)

            = 100*[(0.5*CP)/CP)]

            = 50%

We can also see from Eqn1 that SP is 1.5 times CP. This means that SP is 50% more than CP. This means that Profit is 50%. Profit% is actually the percentage by which SP is higher than CP.
