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 $= 1743\ kg$
Each bag weight $= 49.8\ kg$ 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?
