Find three consecutive largest positive integers such that the sum of one third of first ,one fourth of second and one fifth of third is at most 20.
-------------
1st: x-1
2nd: x
3rd: x+1
------
Equation::
(1/3)(x-1) + (1/4)x + (1/5)(x+1) <= 20
------
Multiply thru by 60 to get:
20x-20 + 15x + 12x + 12 <= 20
-----
47x <= 28
---
x <= 28/47
-----
Comment:: x-1 cannot be a positive integer.
-----
Please check the problem statement.
