A. 57 B. 84 C. 105 D. 111 E. 126

The number of unharmed acres would be \((\frac{8}{11}+\frac{17}{25}+\frac{17}{25}+\frac{1}{9}+\frac{5}{6}+\frac{6}{7})*27\approx{(0.7+0.7+0.7+0.1+0.8+0.9)*27}\approx{3.9*27}\) --> 4*27=108, so 3.9*27 is slightly less than that.

as mentioned seems poor quality, but as you can see the source , its assumed to be a GMAT type . It's part of a free Diagnostic test offered by them, so understandably it has got to be Hard so that you prepare well.
