What is the rate of simple interest?

I. 

The total interest earned was Rs. 4000.

 II. 

The sum was invested for 4 years.

I alone sufficient while II alone not sufficient to answer
II alone sufficient while I alone not sufficient to answer
Either I or II alone sufficient to answer
Both I and II are not sufficient to answer
Both I and II are necessary to answer
Answer: Option
Explanation:

We know that, R = 100 x S.I.
P x T

Now, I gives, S.I. = Rs. 4000.

II gives, T = 4 years.

But, P is unknown. So, we cannot find R.

So, given data is insufficient to get R.

Correct answer is (D).

Yes, I agree with you thanks @Chaitanya Kishore.

S.I per year =1000,
X*4/100 = 1000,
X = 25000
R = (4000*100)/(25000*4) = 4% answer.

Here 100 is not assumed the formula for simple interest is S. I=PTR/100.


That we want R.
So, R = 100 * S. I/P * T.
