Question

 For how many years , Kavitha should invest Rs 10000 at the interest rate of 10% per annum to receive double of invested sum?​

Answer 1

Answer:

10 years

Step-by-step explanation:

Principal = Rs.10000

Amount = Rs.20000

Hence, Simple Interest = Rs.10000

Rate = 10% per annum

Let the time be T.

S.I = P * R * T / 100

10000 = 10000 * 10 * T / 100

T = 10 years
