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

Option D

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

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).
