The total weight of some bags of wheat is 1743kg. If each bag weights 49.8kg, how many bags are there?
Answer
Total weight of bags of wheat = 1743kg
Each bag weight = 49.8kg
No of bags $=\frac{1743}{49.8}$
$=\frac{1743\times10}{49.8\times10}$
$=\frac{17430}{498}$
$=35$
Therefore the total numbers of bags are 35
How many buckets of equal capacity can be filled from 586.5 litres of water, if each bucket has capacity of 8.5 litres?
