Question

Find the value of (0.01)2+(0.22)2+(0.333)2+(0.4444)2+(0.55555)2(0.001)2+(0.022)2+(0.0333)2+(0.04444)2+(0.055555)2\frac{{(0.01)^2 + (0.22)^2 + (0.333)^2 + (0.4444)^2 + (0.55555)^2}}{{(0.001)^2 + (0.022)^2 + (0.0333)^2 + (0.04444)^2 + (0.055555)^2}}​​

A.

50

B.

100

C.

125

D.

75

Correct option is B

Given:

(0.01)2+(0.22)2+(0.333)2+(0.4444)2+(0.55555)2(0.001)2+(0.022)2+(0.0333)2+(0.04444)2+(0.055555)2\frac{{(0.01)^2 + (0.22)^2 + (0.333)^2 + (0.4444)^2 + (0.55555)^2}}{{(0.001)^2 + (0.022)^2 + (0.0333)^2 + (0.04444)^2 + (0.055555)^2}} 

Solution:

(0.01)2+(0.22)2+(0.333)2+(0.4444)2+(0.55555)2(0.001)2+(0.022)2+(0.0333)2+(0.04444)2+(0.055555)2\frac{{(0.01)^2 + (0.22)^2 + (0.333)^2 + (0.4444)^2 + (0.55555)^2}}{{(0.001)^2 + (0.022)^2 + (0.0333)^2 + (0.04444)^2 + (0.055555)^2}} 

​To make the two terms comparable, we can multiply both the numerator and the denominator by 100100100:

100×[(0.01)2+(0.22)2+(0.333)2+(0.4444)2+(0.55555)2]100×[(0.001)2+(0.022)2+(0.0333)2+(0.04444)2+(0.055555)2]\frac{100\times[{{(0.01)^2 + (0.22)^2 + (0.333)^2 + (0.4444)^2 + (0.55555)^2}}]}{100\times[{{(0.001)^2 + (0.022)^2 + (0.0333)^2 + (0.04444)^2 + (0.055555)^2}}]} 

 = 100×[(0.01)2+(0.22)2+(0.333)2+(0.4444)2+(0.55555)2][(0.01)2+(0.22)2+(0.333)2+(0.4444)2+(0.55555)2]\frac{100\times[{{(0.01)^2 + (0.22)^2 + (0.333)^2 + (0.4444)^2 + (0.55555)^2}}]}{[{(0.01)^2 + (0.22)^2 + (0.333)^2 + (0.4444)^2 + (0.55555)^2}]} 

= 100 

the value of the expression is 100
