Step-by-step explanation:

Answer 2

The Amount after 5 years is Rs 11484.8

The compound interest in 5 years is Rs 3484.8

Step-by-step explanation:

Given as :

The principal invested = p = Rs 8000

The rate of interest applied = r = 7.5%   at compounded  p.a

The time period = t = 5 years

Let The amount after 5 years = Rs A

Let The compound Interest credited = Rs C.I

According to question

From Compound Interest

Amount = Principal × $(1+\dfrac{rate}{100})^{time}$

Or,  A = p × $(1+\dfrac{r}{100})^{t}$

Or, A = Rs 8000 × $(1+\dfrac{7.5}{100})^{5}$

Or,  A = Rs 8000 × $(1.075)^{5}$

Or,  A = Rs 8000 × 1.4356

∴    A = Rs 11484.8

So, The Amount after 5 years = A = Rs 11484.8

Again

Compound Interest = Amount - Principal

Or,                       C.I = A - P

Or,                       C.I = Rs 11484.8 - Rs 8000

∴                           C.I = Rs 3484.8

So, The compound interest in 5 years = C.I = Rs 3484.8

Hence, The Amount after 5 years is Rs 11484.8

And  The compound interest in 5 years is Rs 3484.8  Answer
