A

from question :
1735= 125A + 40B +15C
Since we have 3 variables and only other information we can infer is that each of A, B and C should be non negative integer (>=0). Hence, we need to plug in numbers to find out.
Now since the question is asking for 'least' number of rewards, best approach to start with is -finding least 'possible' number of rewards - it can happen when every award is 125. So number of reward in this case 1735/125 = 13 + some remainder. hence ans must be greater than 14.

This gives us
1735 = 13*125 + 40B +15C
or 40B + 15C =110
or 8B + 3C =22
Do we have any combination for B and C that works for this? yes.. if B=C=2.
Hence total number of rewards = A+B+C=13+2+2 = 17

same is given in A.

At this point, some observations could also be made. There could be a doubt in mind, what if A=12 and B+C <5? but note, it is not possible because for every A reduced, difference (125) is to be filled by at least 4 of Bs and Cs (40 and 15 respectively). Second, none of the answer choices is below 17.

Hence Ans A it is.

To get the minimum value, one must maximize the largest price: $125 $$\frac{1735}{125}=\frac{347}{25}=13rem.110$$ Note that $$13*125=1625$$ so we calculate the remaining reward $$40A + 15B = 110$$ Again to get minimum value, maximize the largest remaining reward: $$40$$ $$\frac{110}{40}=2rem.30$$ Note that $$40*2=80$$ so we calculate the remaining reward $$15B = 110 - 80 =30$$ $$\frac{30}{15}=2$$ Thus, 13 + 2 + 2 = 17 Answer: A _________________ Impossible is nothing to God.

Is there a way to solve this question in which i do not have to divide 1735 by 125 and then move forward towards the solution?
