Answer:
120 people [see below]
Step-by-step explanation:
48 out of 120 people like baseball.
That is about 48/120 = 0.4 [40%]
Now, 3/5th of THOSE, play baseball, so
0.4 * 3/5 = 0.4 * 0.6 = 0.24 [24%].
Thus, we have seen that around 24% of total people taken would play baseball.
Now, we take 500 people, so 24% of them would be expected to play baseball.
That is 0.24 * 500 = 120 people
