Explanation: The square and the rhombus are equal in area if they have a common base.

2) If the length is increased by 25%, by what percent the width of a rectangle should be decreased so as to keep the area same. - Published on 06 Jul 15

Explanation: Let the original length be l and the width be b Therefore, the area = l*b Now, as the length is increased by 25%, the new length is (1.25*l) and let the new width be x. As the area is same, 1.25*l*x = l*b x = b/1.25 = 0.8b Therefore, the width is to be decreased by 20%.

3) John, Joni and Janardan start running at same time from the same point on a circular track of 70 meters radius. John and Joni run clockwise and Janardan runs counter clockwise.
