Three stacks containing equal numbers of chips are to be made from 9 red chips, 7 blue chips, and 5 green chips. If all of these chips are used and each stack contains at least 1 chip of each color, what is the maximum number of red chips in any one stack?
(A) 7
(B) 6
(C) 5
(D) 4
(E) 3
My approach is a bit different, 9RC + 7BC + 5GC, total chips can be 315, LCM of all 3 color chips
Now they will be in 3 stacks of equal number of chips, 315/3 = 105 chips/ stack
You can get this from C
9 * 5 + 7 *5 + 5 * 5 = 105
