Question

A man bought watermelons at the rate of 48 for 2,400 and sold them at the rate of 4 for 280. How many watermelons should be sold to earn a profit of 1,200?

Answer 1

Answer:

To earn a profit of 1200, 4 watermelons should be sold for 300.

Step-by-step explanation:

There are 12 sets of 4 watermelons in 48.

Selling all the watermelons for just 280 will only give him a total of

      12*280 = 3360

His profit will only be , 3360 - 2400 = 960

Therefore, he shall sell a set of watermelons for 300.

      12*300 = 3600

Subtracting 3600 from the original price of 48 watermelons which is 2400 gives a profit of 1200.
