If q = 20! + 17, then q is divisible by which of the following?
I. 15
II. 17
III. 19 | [
"None",

"3.0",
"1.5",
"6.0",
"4.0"
] | D | The average of 5 numbers is 6.8
The sum of 5 numbers will be 6.8 x 5 = 34
The average of 5 number after one of the number is multiplied by 4 is 9.2
The sum of the numbers will now be 9.2 x 5 = 46
So the sum has increased by 46-34 = 12
Let the number multiplied by 4 be n
Then,
4n = n+12
or 3n = 12
