Question

I need very mach help see in picture. sixtheenquestions.

Answer 1

Given rate of interest = 5%, Time = 3 years, Simple interest = 1200

We know that Simple Interest I = PRT/100

= > 1200 = (P * 5 * 3)/100

= > 120000 = 15P

= > 8000 = P.

Now,

Principal = 8000, Time n = 3 years, R = 5%.

We know that Amount A = P(1 + r/100)^n

= > A = 8000(1 + 5/100)^3

= > A = 8000(1 + 1/20)^3

= > A = 8000(21/20)^3

= > A = 8000(9261/8000)

= > A = 9261.

We know that compound interest C.I = A - P

= > 9261 - 8000

= > 1261.

Therefore, the compound interest = 1261.

Hope this helps!
