₹8,500 becomes ₹11,050 in 6 years at a certain rate of simple interest. If the rate becomes 1.8 times of itself, the amount of the same principal in 5 years will be:

​Principal, P = ₹8,500

Amount after 6 years, A = ₹11,050

Time, T = 6 years

The rate of interest becomes 1.8 times the original rate for the new scenario.

The formula for simple interest is:

A = P  + Simple Interest (SI)

Where the Simple Interest (SI) is given by:

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

Where R is the rate of interest, P is the principal, and T is the time in years.

Solution: ​
