Answer:
Buying price = x = Rs 750
Profit = Rs 120
Explanation:
Buying price = x
Selling price = Rs 870
Profit = 16% of x
Profit = selling price - cost price
16% of x = 870 - x
0.16 * x = 870 - x
0.16x = 870 - x
0.16x + x = 870
1.16x = 870
x = 870 / 1.16
x = 750
Buying price = x = Rs 750
Profit = 16% of x
= 0.16 * Rs 750
= Rs 120
Profit = Rs 120
