Answer : Option A
Explanation :
The expression is [(0.05)2 + (0.41)2 + (0.073)2]/ [(0.005)2 + (0.041)2 + (0.0073)2]
Or, [(0.05)2 + (0.41)2 + (0.073)2]/ [(0.05/10)2 + (0.41/10)2 + (0.073/10)2]
Or, [(0.05)2 + (0.41)2 + (0.073)2]/ [(0.05)2+ (0.41)2 + (0.073)2] *(1/100)
We know that x/y/100 = x*100/ y
Similarly, [(0.05)2 + (0.41)2 + (0.073)2] * 100/ [(0.05)22 + (0.41)2 + (0.073)2]
Now, the numerator and denominator have the same value, so, they will cancel out each other.
Hence, the value of the expression will be 100.
