Answer:
He paid Rs 1,850 to buy the watch
Profit = Rs 185
Explanation:
Cost price = x
Profit = 10% of x
Selling price = Rs 2035
Profit = Selling price - cost price
10% of x = 2035 - x
0.1x = 2035 - x
0.1x + x = 2035
1.1x = 2035
x = 2035 / 1.1
x = 1,850
Cost price = x = Rs 1,850
Profit = 10% of x
= 10% of 1,850
= 0.1 × 1850
= 185
Profit = Rs 185
