Question

There are two measuring containers of capacities $300mL$ and $750mL$, each. How many times would you use the following containers to take out $15L$ of paint without spillage?
Number of containers with $300mL$ capacity $=P$
Number of containers with $750mL$ capacity $=Q$

• A. $P=20,Q=20$
• B. $P=20,Q=50$
• C. $P=50,Q=20$
• D. $P=50,Q=50$

Answer 1

The correct option is C $P=50,Q=20$

$1L=1,000mL,so15L=15\times 1,000=15,000mL$

First container
Capacity of each container $=300mL$
Number of times the container is used $=15,000÷300=50$

Second container
Capacity of each container $=750mL$
Number of times the container is used $=15,000÷750=20$
Hence, option D is correct.
