A person bought 8 identical articles for a total of ₹20. If he sells each of them for ₹2.6, his profit percentage will be _________%.

Correct option is A

Given:
The person buys 8 identical articles for a total of ₹20.
He sells each article for ₹2.6.

Formula used:

$$\text{C.P. of each article} = \frac{\text{Total cost price}}{\text{Number of articles}}$$

Profir = S.P. - C.P.

$$\text{Profit Percentage} = \frac{\text{Profit}}{\text{C.P.}} \times 100$$

Where,

C.P. is Cost price

S.P. is Selling price

Solution:

C.P. of each article = $$\frac{20}{8}$$​

C.P. of each article = 2.5

Profit per article = 2.6 - 2.5
Profit per article = 0.1

Profit Percentage = $$\frac{0.1}{2.5} \times 100$$​

Profit Percentage = 4%

So, The profit percentage is 4%.

Thus, the correct answer is (a).
