Question

4. On what sum of money will compound
interest (payable annually) for 2 years be the
same as simple interest on * 9,430 for
10 years, both at the rate of 5 percent per
annum ?​

Answer 1

Answer:

please mark brainlist answer We know that

Compound Interest = p(1 + r/100)^n – p

Simple interest = p x r x t /100

Let sum of money be y

So y(1 + 5/100)^2 – y = 9430 x 5 x 10 /100

Y(1 + 1/20)^2 – y = 943 x 5

Y(21/20)^2 – y = 4715

Y(441/400) – y = 4715

Y(441/400 – 1) = 4715

Y(441 – 400 /400) = 4715

Y(41/400) = 4715

Y 41 = 4715 x 400

Y = 1886000 / 41

Y = 46,000

So sum of money will be Rs 46,000

Answer 2

Answer:

9430x5x10÷100=p×(1+r/100)^n -p

94300x5=x-9430

471500+9430=a

480930=a
