If the amount doubles in 10 years, then the rate of interest would be given by the formula
If the amount doubles in 10 years, then the rate of interest would be given by the formulaFV = PV*(1+r)^n or 200 = 100(1+r)^10
If the amount doubles in 10 years, then the rate of interest would be given by the formulaFV = PV*(1+r)^n or 200 = 100(1+r)^10Solving the equation we get, r = {2^(1/10 ) -1} = 1.07177–1 =0.0718 or 7.177% p a

Answer:
In 20 years,the amount will be tripled.
Step-by-step explanation:
Let the amount be x
In case 1:
P = x
T = 10 years
A = 2x
SI = 2x - x = x
By using the formula of SI,
R = 100/10 = 10 %
In case 2:
When amount is tripled,
We have A = 3x
P = x
R = 10 %
S = 3x - x = 2x
T=?
T = 2 × 10
T = 20
Therefore, In 20 years amount will be tripled.
