Answer 2

At 4.13% per annum a sum of ₹1,800 will become ₹2,700 in 10 years

Step-by-step explanation:

Principal = Rs.1800

Amount = Rs.2700

Time = 10 years

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

$2700=1800(1+r)^{10}$

$\frac{2700}{1800}=(1+r)^{10}$

$\sqrt[10]{\frac{2700}{1800}}=(1+r)$

$1.0413 = 1+r$

$1.0413-1=r$

$0.0413=r$

$4.13\% = r$

Hence At 4.13% per annum a sum of ₹1,800 will become ₹2,700 in 10 years
