Best answer
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%
