Question

A water tanker contains $3500litres$ of water. How many buckets of capacity $17\frac{1}{2}litres$ are needed to empty the water tank?

Answer 1

Capacity of one bucket = $17\frac{1}{2}litres=\frac{35}{2}litres$.

Now,

$\begin{array}{rcl}Numberofbuckets& =& \frac{Totalcapacity}{Capacityofonebucket}\\ Numberofbuckets& =& \frac{3500}{{\displaystyle \frac{35}{2}}}\\ & =& \frac{3500\times 2}{35}\\ & =& \frac{7000}{35}\end{array}$

$352007000700$

Hence, the number of buckets required are $200$.
