Question

toffeez are bought at 15 for 20Rs how many toffees would be sold for 20 Rs so as to gain 25percent

Answer 1

Hey there!

Number of toffee bought for 20 Rupees = 15

C. P of 15 toffees = 20 .

C. P of 1 toffee = 4/3 Rs.

To gain, 25 % profit, what should be S. P of each toffee.

Profit % = S. P - C. P / C. P * 100

25 / 100 = SP - 4/3 / 4/3

1/4 * 4/3 = SP - 4/3

1/3 + 4/3 = SP

5/3 = SP.

So each toffee = 5/3 Rs.

Number of toffee that will be bought for 20 Rs = 20 / ( 5 / 3 ) = 20 * 3 / 5 = 12 .

Therefore, By selling 12 toffees for 20 Rs. We will get 25% profit.

Answer 2

Answer:

Hey there!

Number of toffee bought for 20 Rupees = 15

C. P of 15 toffees = 20 .

C. P of 1toffee = 4/3 * Rs .

To gain, 25% profit, what should be S. P of each toffee.

Profit \%=S.P-C . P/C. P * 100

25/10 * O = SP - 4/3 / 4 / 3

1/4^ * 4/3=SP-4/3

1/3 + 4/3 = SP

5/3 = SP

So each - o * ffee = 5/3 * Rs .

Number of toffee that will be bought for 20 Rs=20/(5/3)=20^ * 3/5=12 .

Therefore, By selling 12 toffees for 20 Rs. We will get 25% profit
