A pathway, 6 meters wide, is to be constructed around the boundary of a square lawn using square stone slabs. If the stone slabs cannot be broken, can the stone slabs be used to construct the pathway?

(1) Each side of the square lawn is 50 meters.
(2) Each stone slab has side 4 meters.

Answer B.

The pathway has a width of 6 meters. The square stones have side 4 meters and they cannot be broken. So, basically they cannot be used to construct the pathway.

It's not B because we need to take into account the length of the side of the lawn. In other words, (x+6+6) needs to be a multiple of the length of one stone slab.
1) x+12=50; x=38 (we know the side of the lawn but we don't know the length of a single slab)
2)12 is divisible by 4, but we don't know if x is

Hi alexjst,

Thanks for your explanation. I do agree with it. However, your solution is only mathematically true. Logically if you are to construct a pathway around any square plot then the width of the pathway (in this case 6 m) needs to be a multiple of the stone slab width, if you don't want to break the slab. Moreover, i think GMAT tests not only our mathematical skills, but also our logical skills.

Bunuel Can you please share OE for this question..

I STRONGLY disagree with the question and your explanation aswell !! Width of pathway=6(given) width of square=length of square=4 (Given)
If you carefully draw and see some portions just can't be covered without breaking the slab.
