Find the period.
principal = 9300 rupees
annual rate of interest = 13%
total amount = 17,763 rupees
period =
years

The Time period of the Amount is 5 years 3 days .

Step-by-step explanation:

Given as :

The principal = p = Rs 9300

The annual rate of interest = r = 13%

The Total amount after t years = A = Rs 17,763

Let The time period = t years

From Compound Interest method

Amount = principal ×

Or, A = p ×

Or, Rs 17,763 = Rs 9300 ×

Or, =

or, 1.91 =

Taking Log both side

1.91 = (   )

or, 0.2810 = t × 1.13

or, 0.2810 = t × 0.0530

∴ t -

I.e t = 5.30 years

So, The time period = t = 5 years 3 days

Hence The Time period of the Amount is 5 years 3 days . Answer

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
