or 1 approach could be ..to find LCM of 375 & 600 i.e. 3000 and see how many printers we can buy
3000/600 = 5
3000/375 =8
So,13
Intially I thought the way cramya did...

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:[email protected] wrote:13.

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.
