Answer 2

Answer:

10% profit.

Step-by-step explanation:

Let S.P of 20 pens = ₹ 2000

then, S.P of 1 pen = ₹ 100

Let S.P of 22 pens = ₹2000

Then, C.P of 1 pen = ₹ (2000/22)

= ₹ (1000/11)

Now, profit = (S.P - C.P) = (100 - 11)

Now, Profit = (S.P - C.P) = (100/11)

Profit % = (Profit / C.P × 100) = 10%

Answer: 10%
