Question

By selling 130 cassettes, a man gains an
amount equal to the selling price of 5
cassettes. Find the gain per cent.
​

Answer 1

Answer:

4%

Step-by-step explanation:

Let the cost price of each cassette be Rs.10

The cost price of 130 cassette =130×10=1300

By selling, he gained SP of 5 cassettes

Therefore,  the cost price of 130 cassettes = Selling price of 125 cassettes

SP of 5 cassettes =  $\frac{1300}{125}$ ×5= 52

He gained Rs.52 on selling 130 cassettes

So, Gain %=  Gain/ Total C.P  × 100

                 =  $\frac{52}{1300}$ × 100

                 =4

Therefore gain percent is 4%.
