A man walked diagonally across a square lot. Approximately, what was the percent saved by not walking along the edges?
Answer: Option
Explanation:
Let the side of the square(ABCD) be x metres.
Then, AB + BC = 2x metres.
AC = 2x = (1.41x) m.
Saving on 2x metres = (0.59x) m.
| Saving % = |  |
0.59x | x 100 |  % |
= 30% (approx.) |
| 2x |

AC = root (2x).
Root of 2 = 1.41.
But where did the root of x disappeared?
Root of 2 = 1.41.
But where did the root of x disappeared?

From the fig shown above.
Root of AB square + BC square = AC.
Root of AB square + BC square = AC.

Why do we take the percentage over 2x rather than 1.41x?

saving 2x meters means......
2x-1.41x=0.59x
2x-1.41x=0.59x
