===========================================================================
⇒A.2 and 5
⇒B.3 and 4
⇒C.3 and 5
⇒D.4 and 5

Answer 1

[B] 3 and 4

Step-by-step explanation:

Common Multiples - a number into which each number in a given set can be divided

12/3 = 4

12/4 = 3

36/3 = 12

36/4 = 9

48/3 = 16

48/4 = 12

60/3 = 20

60/4 = 15

Hence, common multiples of 12,36,48,60 is 3 and 4.

Also, Knowing that 12 can't be divide by 5 and the only choice without 5 is [B] 3 and 4.
