There are 35 people in a room. There are
seven more males than females in the room.
How many males are there? How many
females?

14 females

Step-by-step explanation:

Let number of males = x +7

Let number of females = x

Set up the equation:

x + x + 7 = 35

2x + 7 = 35

2x = 28

x = 14

There are 14 females.

(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
