Respuesta :

Answer:

We would solve the above question using the LCM

The 20th Caller will receive both prizes

Step-by-step explanation:

We would solve the above question using the LCM Method

Find and list multiples of 4 and 10 until the first common multiple is found. This is the lowest common multiple.

Multiples of 4:

4, 8, 12, 16, 20, 24, 28

Multiples of 10:

10, 20, 30, 40

Therefore,

LCM(4, 10) = 20

Hence, the 20th Caller will receive both prizes
