Question

A farmer had 640 bag of maize each having a mass of 120kg .After drying the maize, the mass decreased in the ratio 15:16.calculate the total mass lost after the maize was dried?​

Answer 1

72,000kg

Explanation:

So, we know that there are 640 bags.

Each bag has a mass of 120kg.

The mass shrinks at a ration of 15:16

So, we can think of the total mass as 120x640:

120*640

=

76,800kg

Next, we can think of the dried mass as 15/16 of the 76,800kg. This is because the dried ration was 15, and the orgninal ration was 16:

76,800/16

=

4,800kg

This isnt our end answer, next we have to multiply this by 15, to find the dried ration:

4,800*15

=

72,000kg

Hope this helps!
