5. Ram buys some paper wind fans at 4 per rupee. He then buys same number of paper wind fans from another shop at 5 per rupee. He puts them all together and sells them at 4 per rupee. Will he make a profit or incur a loss? How much?

a. Profit = 115/9 %

b. Loss = 115/9 %

c. Profit = 100/9 %

d. Loss = 100/9 %

Answer

Answer: c. Profit = 100/9 %

1 wind fan CP in 1st shop = Rs. 1 and 1 wind fan CP in 2nd shop = Rs. 1

On mixing these 2 wind fans, the cost price of these 2 will be = 1 + 1 = Rs. 9

4 5 20

So, CP of 1 wind fan = 9/20 = Rs. 9

2 40

Actual price at which 1 wind fan is sold after combining = Rs. 1

SP - CP = 1 - 9 = 1 = It is positive; so it is profit
