    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
