Answer:

The first caller who win both a music player and concert tickets is 35th caller.

Step-by-step explanation:

Given : Your local radio station is having their yearly music player and concert ticket giveaway. For one minute, every 5th caller will win a music player and every 7th caller will win concert tickets. You were just the first caller to win both a music player and concert tickets.

To find : What number caller were you?

Solution :

The caller will win both a music player and concert tickets if he lies in group of every 5th caller as well as every 7th caller.

So, we find the first caller who will win both a music player and concert tickets i.e. the L.C.M. of 5 and 7 .

L.C.M. of 5 and 7 is $5\times 7=35$ .

Therefore, the first caller who win both a music player and concert tickets is 35th caller.
