An office requires P sheets of paper each month for each employee. If there are E employees in the office, for how many months will T sheets of paper last?
A. PE/T
B. T/PE
C. TE/P
D. P/TE
E. TPE
The office requires PE sheets per month.
Therefore, the T sheets of paper will last T/PE months.
If the problem appears confusing, choose an easy set of numbers, e.g., P = 30; E = 10 and T = 600.
Then, the office requires 300 sheets (i.e., 30 x 10) per month.
Therefore, the 600 sheets of paper will last 2 months (i.e., 600/300).
