It was actually 300th caller because it has to do with least common multiples, but good guess

Answer:
The station will first give away all three prizes to the 300th caller
Step-by-step explanation:
Radio Station gives :
- 1st prize : $15 to 15th caller
- 2nd prize : $25 to 25th caller
- 3rd prize : free concert tickets to 100th caller
So, in order to get all the three prizes the caller must be 15th, 25th and 100th caller at the same time. But to find when the radio station will give first all three prizes we calculate L.C.M. of ( 15, 25, 100 ) that is 300
Hence, the station first give away all three prizes to 300th caller.
