Question

at what rate percent per annum will ₹50,000 amount to ₹86,400 in 3 years,if the interest is compounded annually?​

Answer 1

Ans. Amount (A)= 86400

Time(n) = 3 years

Principal (P)= 50000

Let rate (r) = r%

Then We Know,

A=P×(1+r100)n

=>86400=50000×(1+r100)3

=>8640050000=(1+r100)3

=>216125=(1+r100)3

=>(65)3=(1+r100)3

On comparing, We get

=>(65)=(1+r100)

=>65−1=r100

=>15=r100=>r=20%
