A) 0.1662
B) 0.1993
C) 0.3412
D) 0.5126
Correct Answer: B
Solution :
\[\Rightarrow \] At equal \[{{(1-x)}^{2}}=9{{x}^{2}}\] \[\Rightarrow \] \[{{1}^{2}}+{{x}^{2}}-2x=9{{x}^{2}}\]Antilog \[\Rightarrow \] \[8{{x}^{2}}+2x-1=0\] \[\Rightarrow \] \[8{{x}^{2}}+4x-2x-1=0\] \[\Rightarrow \] % dissociation \[(2x+1)\,(4x-1)=0\] = 0.1995You need to login to perform this action.
