In a ratio, we do not require the exact numbers..

We are looking for B/C..
Let's see the statements

(1) The number of Chipmunks fans among the spectators is 20% greater than the number of Bullfrogs fans.
So C=B+20..... C and B are in %
Also C+B=100...
B+20+B=100...
2B=80.... B=40..
C=100-40=60
Ratio =60/40=3/2

Sufficient

(2) The total number of spectators at the baseball game is 4,400.
Total is given ONLY to tempt you towardsC..
Insufficient

A
