Q:

If each side of a square is increased by 25%, find the percentage change in its area.

A) 56.25% B) 36.25%
C) 16.25% D) 12.25%
 
Answer & Explanation Answer: A) 56.25%

Explanation:

Let each side of the square be a. Then, area = .a2
New side =125a100=5a4. New area = 5a42 = 25a216

 

Increase in area = 25a216-a2=9a216
Increase% = 9a216*1a2*100 % = 56.25%.

A) 1080 B) 1090

 C.I=x*50300*1003-x=343x216-x=127x216 

 

127x216=1270 

 

x=2160 

 

Thus, the sum is Rs. 2160

 

 S.I=Rs.2160*503*3*1100=Rs 1080
