Question

the time by which a sum of money would treble itself at 8% p.a C.I is​

Answer 1

Answer:

10 years.

Step-by-step explanation:

Let the principal be x

So, Amount = Double of principal = 2x

Rate of interest = 8%

Formula : A=P(1+r)^tA=P(1+r) t

2x=x(1+0.08)^t2x=x(1+0.08) t

2=(1+0.08)^t2=(1+0.08) t

t=9.006t=9.006

t\sim 10t∼10

So, a sum of money double itself at 8% p.a in 10 years.
