Answer:

The sum would be 3000 rupees.

Step-by-step explanation:

Let sum is P,

Since, the simple interest formula is,

I=P\times r\times t

If r = 10% = 0.1, t = 3,

Simple interest is,

I_1=P\times 0.1\times 3 = 0.3P

Now, the compound interest formula,

I=P(1+r)^t-P

So, the compound interest is,

I_2 = P(1+0.1)^3 - P = P(1.1)^3 - P = 1.331P-P = 0.331P

According to the question,

I_2-I_1=93

0.331P-0.3P = 93

0.031P = 93

\implies P = \frac{93}{0.031}=3000

Hence, the sum would be 3000 rupees.
