Instructions

In each of these questions, two statements I and II follow a question. Mark your answer as:

Question 120

Meena wants to Find $$\log_{70} 96$$.
I. She knows the value of $$\log_{96} 70$$
II. She knows the value of $$\log_{10} 70$$

Solution

Using statement I, we know that $$\log_{96} 70=k$$ (say)

Now, $$\log_{70} 96=$$ $$\frac{1}{\log_{96} 70}=\frac{1}{k}$$

Thus, I statement is sufficient alone.

But, we cannot get the solution using second statement alone.

Thus, the question can be answered by using only one statement alone, but not by using another statement alone.

=> Ans - (A)
