Correct option is D
Given:
70% of articles are sold at a profit of 20%, and the remaining are sold at a loss of 10%.
Formula Used:
Overall Profit % = (Sum of individual profits and losses) / (Total Cost Price) × 100
Solution:
Let the CP of 100 Article = Rs. 100
Condition first:
SP of the 70% articles = 70 * 120% = 84
Condition second:
SP of the 30% articles = 30 * 90% = 27
Total SP = 84 + 27 = 111
Now, Total profit = SP – CP = 111 – 100 = 11%
