Question

at what rate of intrest will the sum of money dobule itself in 5 yrs​

Answer 1

I think this is the answer

P = 2x

T = 5

SI = x

SI = PTR/100

100x = 10x * R

R=10%

Answer 2

Answer:

20% Per Year. 20x5=100%

100% your capital which you want to invest and rest of the 100% you will get

100+100 become 200% it means double.
