If 8 tigers were added to the zoo, the new ratio of lions to tigers would be 4 to 3. How many bobcats are at the zoo?

A. 4
B. 8
C. 12
D. 24
E. 48

Use Ratios:

Current Lions:Tigers = 32:8 = 4:1
New Lions:Tigers = 4:3

The number of lions stay the same. We do have the same 4 in both ratios. Hence the difference of 2 on the ratio scale in number of tigers is actually equal to 8 (since 8 tigers were added). So the multiplier is 4.

Current Lions = 4*4 = 16
Ratio of Lions:Bobcats = 32:24 = 4:3
Number of bobcats then = 3*4 = 12

Answer (C)

A. 4
B. 8

E. 48

We can let t = total number of cats in the zoo. The current number of lions is 0.32t, and the current number of tigers is 0.08t. If we add 8 tigers, the number of lions will be unchanged, but the new number of tigers will be (0.08t + 8). We can create the equation:

0.32t/(0.08t + 8) = 4/3

32t/(8t + 800) = 4/3

96t = 4(8t + 800)

96t = 32t + 3200

64t = 3200

t = 50

Therefore, there are 0.24 x 50 = 12 bobcats in the zoo.

Answer: C
