Answer 2

Answer:

Brand A = 35

Brand B = 28

Brand C = 20

Step-by-step explanation:

The math given below is based on LCM property. There we need to find the LCM of 12, 15, 21

LCM of 12, 15, 21 = 2 × 2 × 3 × 5 × 7

= 420

Therefore, Brand A = 420/12

= 35

Brand B = 420/15

= 28

Brand C = 420/21

= 20
