Question

Hamad sells fruits in his shop. One morning, he got 2 boxes of apples from 2 different
suppliers.

The label on the first box says that it contains 50 apples with a total weight of 6300 g.

The label on the second box says that it contains 40 apples, and has a mean weight
of an apple of 144 g.

Hamad put all the apples from both boxes in one big container.

Find the mean weight of an apple in the big container.

Answer 1

The weight of all 40 apples in the second box is : 144 x 40 = 5760 (g)

The total weight of all 90 apples in both boxes : 5760 + 6300 = 12060 (g)

To find the mean weight of an apple in the big container, we take the total weight of both boxes (12060) divided by the total amount of quantities (apples in both boxes)

So, the mean weight of an apple in the big container is 12060 : 90 = 134(g)
