Hi Musicat,
This question can be solved by TESTing VALUES.
IF...
M = 2
N = 3
Then we know that 2 liters are required per household per month and that there are 3 households in the village. In this scenario, we will need 6 liters per month.
P = 12 liters means that this water will last for 2 months, so we're looking for an answer that equals 2 when we plug in the three VALUES chosen.
There's only one answer that matches..
Final Answer: A
