A factory producing tennis balls stores them in either big boxes, 25 balls per box, or small boxes, 17 balls per box. If 95 freshly manufactured balls are to be stored, what is the least number of balls that can be left unboxed?

I think we can put that as 25X1+17X4=93 hence 2 is the answer ; I tried by checking for 94, 93 from the answer options and think is the quickest (took 1 min)

1 2 3 4 5
25*3 + 17 = 92 so C.3 should be the answer
I think the answer is B - 2. 25*1 + 17*4 = 93. I don't think there's an quick way example plug in numbers starting with multiples of 25.

Thanks all, Oa is B

In theory, I think maximum 3 times 25, and then force times of 17 as above. But this question does not follow the theory? What do you think? Thanks! _________________

why not 0
the question does not state that the boxes have to be full.
I agree, this question is worded horribly. You could fill the 75 balls into 3 of the large boxes and then put the remaining 20 balls into another large box and still have room for 5 more balls. Answer should be zero. Now, if they asked what is the least number of boxes that could be used, that would make more sense. _________________

Do we have a nice and elegant approach for solving this one? Tried first with 17*4 = 91. Then since I thought it was too easy gave it a second shot with 25*3 + 17 = 92. But I wasn't expecting 2 as the answer. Very tricky
Will provide Kudos for some nice and short approaches Cheers J

The only "fast" approach identified by me is the following:
1. Put possible combinations in two columns:
17 25 34 50 68 75 85
2. Start picking two units digits from each row to get the greatest possible unit digit in the possible final combinations (descending order) - 94 -> 93 -> 92 > 91 -> 90
in 94 it is 4 => 50 + 34 -> no in 93 it is 3 => 25 + 68 = 93, got it!
