Each of the questions given below consists of two statements numbered I and II given below it. Please read the questions carefully and decide whether the data provided in the statement(s) is / are sufficient to answer the given question.

1)

Calculate the rate of $SI$ ?

I. The total interest earned was Rs. $4000$.

II. The sum was invested for $4$ years.


A) I alone sufficient while II alone not sufficient to answer

B) II alone sufficient while I alone not sufficient to answer

C) Either I or II alone sufficient to answer

D) Both I and II are not sufficient to answer

E) Both I and II are necessary to answer

Answer:

Option D

Explanation:

$R$ $=\left(\frac{100\times SI}{P\times T}\right)$

Now, I gives, $SI$ = Rs. $4000$.

II gives, $T$ $=4$ years.

But, we cannot calculate $R$ since $P$ is unknown.

So, given data is insufficient to get $R$

$\therefore$ Correct answer is (D).
