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. ##### General Discussion Director Status: Done with formalities.. and back..

If the total reward is $1,735, what is the least possible value of the number of the people who received reward? a. 17 b. 22 c. 32 d. 47 e. 90 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. So we can start with A=13 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. _________________ Lets Kudos!!!

The way I did it was I saw that to get the least possible value of number of people, I had to get the most number of$125 people and minimise the rest of the two cash values, knowing what's left after taking the $40 and$15 into consideration must be a multiple of 125.

40 + 15 = 55.
1735 - 55 = 1680 clearly not a multiple of 125

2*(40 + 15) = 110
1735 - 110 = 1625 A-ha!

1625 / 125 = 13

$125 |$40 | $15 So 13 + 2 + 2 --> 17 Target Test Prep Representative Status: Head GMAT Instructor Affiliations: Target Test Prep Joined: 04 Mar 2011 Posts: 2823 Re: A certain organization presents reward to some people...

If the total reward is $1,735, what is the least possible value of the number of the people who received reward? a. 17 b. 22 c. 32 d. 47 e. 90 We can let a, b, and c = the number of$125, $40, and$15 reward recipients, respectively, and create the equation:

125a + 40b + 15c = 1,735

25a + 8b + 3c = 347

To minimize the sum a + b + c, we want first to make a as large as possible, then b as large as possible and then c as large as possible.

Since 347/25 = 13 R 22, we can let a = 13. (Notice that 25 x 13 = 325 and 347 - 325 = 22.)

Since 22/8 = 2 R 6, we can let b = 2. (Notice that 8 x 2 = 16 and 22 - 16 = 6.)

Finally we can see that c = 2 since 6/3 = 2.

Thus, the minimum number of people is 13 + 2 + 2 = 17.
