Answer: 19200
Step-by-step explanation:
Loss incurred on selling TV = 5%
Let the CP of the TV = x
SP of the TV = 0.95x
New SP of the question = (0.95x + 2880)
Profit = (0.95x + 2880) - x = (2880 - 0.05x)
Profit = (2880 - 0.05x) - x
Profit % = {[(2880 - 0.05x) - x] / x} × 100
10 = {[(2880 - 0.05x) - x] / x} × 100
10/100 = {[(2880 - 0.05x) - x] / x}
x = 28800 - 0.05x
1.5x = 28800
x = 28800 / 15
x = 19200
