A) 24
B) 32
C) 12
D) 48
Correct Answer: C
Solution :
\[\frac{x}{x-1}+\frac{x-1}{x}=2\frac{1}{2}\] (\[(5,4)\] numerator in both rations is same) \[=\sqrt{9\times 49\times {{10}^{-2}}}=\sqrt{{{\left( 3\times 7\times {{10}^{-1}} \right)}^{2}}}\] \[=3\times 7\times {{10}^{-1}}=2.1\]\[x+y=2\]You need to login to perform this action.
