Question

Q. Find the rate at which Rs.4,000 will give Rs.630.50 as compounded quarterly in 1 year?​

Answer 1

Step-by-step explanation:

Principal = 4000 amount = 4630.50 t = 4 ( as it is compounded quarterly)

a = p×(1+r/100) ^t

4630.50 = 4000(1+r/100)^4

4630.50/4000=(1+r/100)

463050/400000. = (1+ r/100)

463050/400000 = 1 + r^4 / 100000000

463050/400000 - 1 = r^4/100000000

463050-400000 /400000 = r ^4/100000000

63050/400000 × 100000000 = r^4

15762500 = r^4

r = 15762500 ka 4 wala root

now you can solve this
