Question

At what rate of interest will Rs. 4500 get doubled, in a period of 10 years?​

Answer 1

Answer:

10%

Step-by-step explanation:

principle=4500

time=10 years

amount=2*principle

=2*4500

=9000

interest = amount-principle

=9000-4500

=4500

for simple interest

interest = p*R*t/100

4500 =4500*R*10/100

4500 =450*R

R =4500/450

=10%

Answer 2

Answer:10%

Step-by-step explanation:

The total amount after 10 years will be double of 4500 I.e 9000.

Now,

Interest=P*N*R upon 100.

4500=4500*10*R upon 100

4500=450*R. 4500 upon 450=R

10=R

I.e R=10%
