Final answer:
To find the number of years it will take for the compound interest on Rs 16000 at a rate of 5% per annum to be Rs 18522, we can use the formula for compound interest.
Step-by-step explanation:
To find the number of years it will take for the compound interest on Rs 16000 at a rate of 5% per annum to be Rs 18522, we can use the formula for compound interest:
Compound Interest = Principal x (1 + Rate/100)^Time - Principal
18522 = 16000 x (1 + 5/100)^Time - 16000
After solving this equation, we find that the time needed is approximately 5 years.
