-
A.

-
B.
Gain of 20%
-
C.
Gain of 40%
-
D.
Loss of 30%
Correct Answer:
A. Gain of 33.33%
Explanation:
To find the gain or loss percentage, first determine the cost price (CP) and selling price (SP) for a single unit.1. Calculate the CP of one pen: If 8 pens cost Rs.40, then the CP per pen is 40 / 8 = Rs.5. 2. Calculate the SP of one pen: If 6 pens are sold for Rs.40, then the SP per pen is 40 / 6 = Rs.6.67. 3. Determine profit or loss: Since the SP (Rs.6.67) is higher than the CP (Rs.5), there is a gain. 4. Calculate the gain amount: Gain = SP - CP = 6.67 - 5 = Rs.1.67. 5. Calculate the gain percentage: Gain % = (Gain / CP) \* 100 = (1.67 / 5) \* 100 = 33.33%.Therefore, there is a gain of 33.33%.
