Question

Answer 1

Answer:

10%

Step-by-step explanation:

Percentage is calculated per 100.

If the dealer defrauds his customers 5% in purchasing and a 5%  in selling on a whole of 100%, that means he is obtaining a profit of 10% as a whole.

Purchasing = He gains 5%

Selling = He gains 5%

So, he gains a total profit of 10% gain.

Answer 2

Answer:

Total gain percentage of the dealer is 10.25%

Step-by-step explanation:

Let us assume the original cost price of the product he purchased is Rs.100

If he had cheated by 5%, then he must have received the product quantity amounting to gain of 5% of 100 = Rs.105

Now, again if he cheats 5% while selling the product, then it means he is selling at a gain of 5%.

That is, 105*5/100 = Rs.110.25

Total gain = 110.25 -100 = Rs.10.25

Total gain percentage = 10.25 *100/100 = 10.25%
