Q.  The length of a rectangle is increased by 60 %. By what percent would the width have to be decreased to maintain the same area?

a. 37 ½ %
b. 60 %
c. 75 %
d. none of these


ANSWER: See Answer
 
Let length = 100 m.

Breath = 100 m.

New length = 160 m.

New breath = x meters

Then, = 160 × x = 100 × 100

(or) X = (100 ×100)/160 × 125/2

Decrease in breadth = (100- 125/2) % = 37 ½ %
