Question

A man walked diagonally across a square lot. Approximately, what was the percent saved by not walking along the edges?

Options:

A . 20

B . 24

C . 30

D . 33

Answer: Option B

Let the side of the square(ABCD) be x metres.

Then, AB + BC = 2x metres.

\(AC = \sqrt{2x}=(1.41x)m.\)

Saving on 2x metres = (0.59x) m.

Saving % = \(\left(\frac{0.59}{2x}\times100\right)\) % = 30% (approx.)
