In how many years will rupees 2000 amount to rupees 2420 at 10% per annum compound interest.

Given,

P= Rs 2000

A= Rs 2420

R= 10 %

A = P(1 + R/100)ⁿ

⇒2420 = 2000(1 + 10/100)ⁿ

⇒2420/2000 = (11/10)ⁿ

⇒121/100 = (11/10)ⁿ

⇒(11/10)² = (11/10)ⁿ

⇒n = 2

∴ In 2 years rupees 2000 will amount to rupees 2420 at 10% per annum compound interest.
