Correct Answer - Option 3 : 16%
Calculation:
Let the number of Mobile A units sold is 2n,
Mobile B units sold = 3n
Let P Be the cost price of each mobile unit.
Total revenue = 2n × 1.1 P + 3n × 1.2 P = 5.8 Pn
Total cost = 5 Pn
Total profit = 5.8 Pn - 5 Pn = 0.8 Pn
Profit percentage = ((0.8 Pn)/5 Pn) × 100 = 16%
