Answer

Q15)
Answer: d)0.04
Explanation:
from the question when the X value is something the whole
value of the equation will be perfect square.
afetr 11 the no.12 is a whole number so square of 12 is
144. So we take
(11.98*11.98)+(11.98*X)+(0.02*0.02)=144
from this X=0.04

Answer

Q1). The length of rectangle is increased by 15% and its
breadth is decreased by 15%. The are of new rectangle is

Ans: b) decreased by 2.25%
Explanation:
Consider original Length & breadth of rectangle is X, Y
respectively. So area=1XY
After increased length of 15% = X+0.15X=1.15X
After decreased breadth of 15% = Y-0.15Y=0.85X
So area of new rectangle=1.15X*0.85Y=0.9775XY
From these
1XY-0.9775XY=0.225XY
So the percentage of area decreased by 2.25%
