Question

Find the rate when
principal = ₹4400, Amount = ₹5610 and time = 5 year 6 month

Please explain in step by step.​

Answer 1

Answer:

Thus, n = 5.5 years. A = 5610 and P = 4400. 5610 = 4400 + 4400*5.5*r/100, since we have to find r. Thus, rate of interest is 5%

Answer 2

in this case, 5 years 6 months can be written as 5 6/12 = 5 1/2 or 5.5 years.

Thus, n = 5.5 years.

A = P + SI and SI = Pnr/100

A = 5610 and P = 4400.

5610 = 4400 + 4400*5.5*r/100, since we have to find r.

5610 - 4400 = 4400*5.5*r/100

1210 = 4400 * 5.5*r/100

Or r = 1210 * 100 / (4400*5.5)

r = 121000/24200 = 5%

Thus, rate of interest is 5%.
