WAEC Agriculture 2012 Paper

Question : 37

Total: 49

Solution:

Concept:

The number of pigs is found by dividing the total floor area of the pigsty by the floor space required for one pig.

Explanation:

The pigsty has a length of

5.0\ \mathrm{m}

and a breadth of

4.0\ \mathrm{m}

Total floor area

= 5.0 \times 4.0 = 20.0\ \mathrm{m}^2

One pig requires

2.0\ \mathrm{m}^2

of floor space.

Number of pigs

= \frac{20.0\ \mathrm{m}^2}{2.0\ \mathrm{m}^2} = 10

Therefore, the pigsty can house exactly

10

pigs.
