Answer 1

Given,

Total cost price = Rs. 2000

Total lamps = 10

Total profit = Rs. 7240

To find,

The selling price of each lamp that will produce the given amount of profit.

Solution,

We can easily solve this mathematical problem by using the following mathematical process.

10x = 9240

x = 924

Hence, the necessary selling price of each lamp will be Rs. 924
