Answer:
The station first give away all three prizes to 300th caller.
Step-by-step explanation:
A radio station gives away $15 to every 15th caller, $25 to every 25th caller, and free concert tickets to every 100th caller.
To get the answer we need to calculate L.C.M. of 15, 25, 100.
15 = 3 x 5
25 = 5 x 5
100 = 2 x 2 x 5 x 5
LCM is = 2 x 2 x 3 x 5 x 5 = 300.
Hence, the station first give away all three prizes to 300th caller.
