What is the rate of simple interest? | |
I. | The total interest earned was Rs. 4000. |
II. | The sum was invested for 4 years. |
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).

S.I per year =1000,
X*4/100 = 1000,
X = 25000
R = (4000*100)/(25000*4) = 4% answer.
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.
That we want R.
So, R = 100 * S. I/P * T.
