Question

3.If the amount on Rs 6400 after 2 years is Rs 7396, find the rate of compound Interest?​

Answer 1

Answer: Hey mate hope it is helpful

The amount is Rs 7396 and the compound interest is Rs 996...

Step-by-step explanation:

Find the compound interest on $ 6400 for 2 years, compounded annually at 7¹/₂ % per annum.

Solution:

Here, P = $ 6400, R % p. a. and n = 2 years.

Using the formula A = P (1 + R/100)ⁿ

Amount after 2 years = [6400 × {1 + 15/(2 × 100)}²]

= $ (6400 × 43/40 × 43/40)

=$ 7396.

Thus, amount = $ 7396

and compound interest = $ (7396 - 6400)

Therefore, compound interest = $ 996.

Answer 2

                                                                                                                 

• Answer:

compound interest = $996

                                                                                                                 

• Step-by-step explanation:

                                                                                                                 

compound interest = (A)amount - (p)principal

Amount = $7396

principal = $6400

compound interest = 7396 - 6400

compound interest = $996

                                                                                                                 

suppose that in the que we have no amount so ,

we can us this formula = $A= p(1+\frac{r}{n} )^{n}$

and take amount and

using this formula "compound interest = (A)amount - (p)principal"

and solve
