Question

There are 48 cricket balls, 72 hockey balls and 84 tennis balls and they have to be arranged in several rows in such a way that every row contains the same number of balls of one type. What is the minimum number of rows required for this to happen?​

Answer 1

Answer:

Answer- 12

Step-by-step explanation:

H.C.F. of 48, 72, 84

i.e., 48 = 2 X 2 X 2 X 2 x3

72 = 2 x 2 x 2 x 3 x 3

84 = 2 x 2 x 3 x 7

H.C.F. = 2 x 2 x 3 = 12

Hence minimum number of required row is 12.
