Question

The question is followed by two statements numbered I and II. Mark answer as:
If the expression $x^2-4x+3.75=0$ is true, what is the unique value of $x$ ?
I. $x$ is a positive real number.
II. $x$ is less than $(1+\frac{1}{n})^n$, where n is a positive integer.

• A. statement I alone is sufficient to provide the answer.
• B. statement II alone is sufficient to provide the answer.
• C. both statements are required to provide the answer.
• D. neither statement I nor II is sufficient to provide the answer

Answer 1

Answer: (D)

neither statement I nor II is sufficient to provide the answer

Answer 2

From statement I
x=2.5 or 1.5
Statement II
also does not give any unique value.
Hence neither statement I nor II is sufficient to provide the answer.
So the correct option is (D)
