If the compound interest on ₹30,000 at a 7% annual interest rate is ₹4347, what is the time period?

A.

2 years

B.

2.5 years

C.

3 years

D.

4 years

Correct option is A

Given:

Principal =  ₹30,000 at a 7%

Compound interest =  ₹4347

Solution: 

P =30,000 

Interest of First Year = 30000×7100=30000 \times \frac{7}{100} = ​2100

Interest of Second Year = 2100  + 2100×7100=147{2100 }\times \frac{7}{100} = 147 

Total interest of two years = 2100 +  2100 + 147  = ₹ 4347  

Time period = 2 years
