Question

If P=8000, R=10%, Amount=12000 then period T is _______

Answer 1

Answer:

P= ₹8000, R= 10%, Amount = ₹12,000, then period is

Answer 2

Given - Principal, rate of interest and amount

Find - Time period

Solution - The time period T is 5 years.

Firstly calculating interest from principal and amount.

Amount = Principal + Interest

Interest = 12000 - 8000

Interest = 4000

Secondly putting the values in the formula of simple interest.

Simple interest = Principal*Rate of Interest*Time/100

4000 = 8000*10*Time/100

Time = 4000*100/(8000*10)

Cancelling the zeroes and performing multiplication and division to find the time period.

Time = 5 years

Hence, the time period is 5 years.
