A wildlife preserve is being planned for 3,000 rhinoceroses. [#permalink]  05 Jan 2004, 19:22
A wildlife preserve is being planned for 3,000 rhinoceroses. The preserve is to contain a total of 10,000 acres of watering area, plus 100 acres of grazing area for each rhinoceros. If the number of rhinoceroses is expected to increase by 10 percent, how many thousand acres should the preserve have in order to provide for the increased population?

A 340
B 330
C 320
D 310
E 300

Well, make an equation in the form of a line:
y=mx+c; c=10000, x=3000 and m=100 y is a required preserve
bcoz there is one not changing part i.e. watering area and one part which is changing i.e. no of rhinoceroses.
y=3,10,000 in first case.
Now, if rhinoceroses will become 3300 then,
y=3300*100+10000 =3,40,000 = 340 thousands (A) is the answer

Hope this helps, Dharmin

10% increase - 300 --> 3300 rhinos. man..!

each needs 100 acres of grazing area, thus
3300 * 100 = 330 thousand acres.

plus, a 10,000 acres watering area = 10 thaousand acres

total 330+10 = 340 thousand acres

The wording threw me off.

My girlfriend, an attorney, solved it in under 30 seconds. Quite humbling!
