Question

9000rs become 18000rs at s.i in 8 years find the rate % at s.i​

Answer 1

Answer:

Hey,

Amount = 18000

Principal = 9000

So, Simple Interest = Amount - Principal

= 18000 - 9000

= 9000 .

So,

Simple interest = PRT / 100

9000 = 9000*R*8 / 100

9000 and 9000 is cancelled,

R = 25/2 % or 12.5 % per annum.

Hope this helps you buddy !!
