Another way:

As the total cost of 2 types of printers are same. Hence:

600*a = 375 * b (where a and b are the number of printers of each type).
=> 8a = 5b . The least value for which it is possible is for a = 5 and b = 8.
So total 8+5 = 13

The smallest amount that the company can spend is the LCM of 600 and 375, which is 3000.
The fewest number of computers they can purchase is therefore 3000/600 + 3000/375 = 13

Option (A)

The smallest amount that the company can spend is the LCM of 600 and 375, which is 3000 for each, which is total 6000.
The number of 1st type of computers which costing $600 = 3000/600 = 5.
The number of 2nd type of computers which costing $375 = 3000/375 = 8.

Total = 5+8 = 13
Answer is A.

Cheers!

LCM of 375 and 600 is 3000

3000/600 + 3000/375 = 13

A

Nice job, didn't think about it

here's how I did it

600a=375b - divide 25
24a=15b -divide by 3
8a= 5b...5+8=13

I found it just as easy to count by 375, until I recognized a number that would be divisible by 600. I knew it would come quick and by easily recognizable.

2 * 375 = 750
double that for
4 * 375 = 1500
double that for
8 * 375 = 3000 which is clearly the first number that is divisible by 600 (5 * 600).

8 @ 375 and 5 @ 600 = 13

Of course all of the previously mentioned solutions worked just as well, and probabaly as fast, but this is what worked best for me.

(A) 13

(C) 10
(D) 8
(E) 5


We can let a = the number of $600 printers purchased and b = the number of $365 printers purchased. Since the same number of dollars were spent purchasing each type of printer, we can create the following equation:

600a = 375b

24a = 15b

8a = 5b

In order for 8a to equal 5b, the smallest value of a is 5 and the smallest value of b is 8, and thus the minimum number of printers that can be purchased is 8 + 5 = 13.

Answer: A
