In how much time will a sum of Rs. 10200 amounts to Rs. 19125 at the rate of 12.5 percent per annum at simple interest?

Principal (P) = Rs. 10,200

Amount (A) = Rs. 19,125

Rate of interest (R) = 12.5% per annum

Time (T) = ?

Simple Interest (SI) = A - P

Formula for Simple Interest:

SI = $$\frac{P \times R \times T}{100}$$​​

Solution: 

Simple Interest, S.I. = 10200 - 19125 = 8925 

So, Applying the formula,
