If one is added to the numerator of the fraction it becomes one. If one is added to the denominator of the fraction it becomes 1/2. The fraction is?
Answer: C
Let the fraction be x/y.
=> (x+1)/y = 1
=> x+1 = y—(1) x/(y-1) = 1/2
=> 2x = (y+1)—(2)
=>Equating (1) and (2)
=> x+1 = 2x-1
=>x=2
Substituting the value of x in (1)
=>y=3
=>2/3
