Question

How many numbers are there in the range (6..9)?

Answer 1

Explanation:

LCM of 6 and 9: 18

>6=2*3

>9=3*3

What is the highest multiple of 18 under 100?

>200-100=100

90 = 18*5

Calculate the first starting position, 108

>108=18*6

If 108 + 90 < 200 AND 200–(108+90) < 18

then 90/18 is the answer.

The answer is 5
