Question
 A, B C D are squares. Ravi wants to go from A to C. If
he wants to go diagonally instead of sideways, then what percent less distance will he have to cover?              ÂSolution
Let the side of the square = 100 When Ravi goes from A to C instead of sideways =100+100 =200 When he goes diagonally = a√ 2  = 100 ×1.41 = 141 Distance reduction = 200 -141 = 59 reduction = 59/200 ×100 = 29.5%
