There are 12 numbers between A and B. All these numbers are multiples of 6. The first number after A is 18. Find the value of B?
- 90
- 95
- 100
- None of these
Explanation
Numbers are multiples of 6, and first number after A is 18
So the numbers are: 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84
That’s 12 numbers total
Last number = 18 + (12-1)×6 = 18 + 66 = 84
B comes right after the last number, and B also must be a multiple of 6
Next multiple of 6 after 84 is 84 + 6 = 90
