Question

A shopkeeper sells 12

toffees for Rs.25 and he

get 20% loss how many

toffees should he sells

in Rs. 25 so he get 20% profit​

Answer 1

Answer:

The man sells 12 toffees for a rupee. Means he sells toffees worth 12 rupees.

But while doing so, he loses 20%. This 20% is nothing but 20% of the cost price.

So,

Let his cost price be x.

Now,

x — (x×0.2) = 12. (From the given data)

x * 0.8 = 12.

x = 15.

Now we know that the cost price of toffees was 15 Rs.

Next statement in the question asks how many toffees the man should sell for a rupee to gain 20% profit. (Assumption here is the toffees being refered to in both statements of the question are the same and hence will have the same cost price)

20% profit means 1.2 * CP (cost price)

Means, 1.2 * 15 which equals 18 Rs.

Now let's assume number of toffees to be sold at 1 Re to be n.

Mathematically,

n * 1 = 18

Hence, n=18.

So the man needs to sell 18 toffees to get 20% profit.
