Question
A man walked diagonally across a square plot. Approximately what was the percent saved by not walking along the edges?
Options
A. 10%
B. 20%
C. 30%
D. 40%

Correct Answer

30%

length of two sides = 2x meters
diagonal = $\sqrt{2 x}$ = 1.414x m

saving on 2x meters = .59x m

saving % = $\frac{0.59 x}{2 x} * 100$ %

= 30% (approx)
