Let X= 133.
1: suppose the combination contains 87
87 125 128 133 137 143
87 X-8 X-5 X X+4 X+ 10
1 1 3 6 8 2
4 & lt(700-87)/ 133 & lt; five
4X+87=532+87=6 19
The maximum value is 6 19+ 10 * 2+4 * 2 = 647.
5X+87=752
The minimum value is 752-8-5 * 3 = 729 >; 7 10
87 no solution
2 Suppose the combination does not contain 87.
5 & lt700/ 133 VI
5X=665
The maximum value is 665+ 10 * 2+4 * 3 = 697.
6X=798
The minimum value is 798-8-5 * 3 = 775 >; 7 10
So there is no solution to this problem.
