The number of light bulbs sold each day in two different hardware stores is represented in the box-and-whisker plots below. Which store's median number of light bulbs sold is greater?

A.

Store A

B.

Store B

C.

both the same

D.

cannot tell from given plots

A. Store A

Step-by-step explanation:

The median is shown by the very middle line of the box. The middle-most line on the box of store A is greater than that of Store B

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
