Answer 1

Answer:

40% profit

Step by step Explanation:

Profit percentage

=( profit/cost price) * 100

0.2 = profit/cost

10+15+20+25+30= 100

Let's assume the cost price of the items is $1 each

Cost price total= $100

Profit made when buyer of 20 toffe didn't say was

0.2=profit/cost

0.2*100 =$20

If the$ 20 paid.

Total profit = $40

So percentage profit now

40/100 * 100 = 40%

Answer 2

The shopkeeper makes a loss of 40% and this can be determined by using the given data.

Given :

• 5 customers buy 10,15,20,25,30 toffees respectively from 1 shop.
• But the person who bought 20 toffees forgot to pay.
• The shopkeeper makes a 20% profit.

The following steps can be used in order to determine the profit or loss the shopkeeper makes:

Step 1 - The total number of toffees can be calculated as:

$\rm Total \; Toffees = 10 +15 + 20+ 25+ 30\\\rm Total \; Toffees = 100$

Step 2 - Now, let the cost of 1 toffee be $1. So, the cost of 80 toffees is $80.

Step 3 - So, the value of 20% profit by selling 80 toffees be 'x'. So, the value of 'x' is:

$x = \dfrac{20}{100}\times 80$

$x = \ 16$

Step 4 - Now, let the profit or loss be 'y'. So, the value of 'y' is:

$y = \dfrac{20}{80}\times 16$

$y = \ 4$

Step 5 - So, the loss percentage is 40%.

Therefore, the correct option is C).
