1. Find the unknown quantity in each of the following:
principal -400
rate of interest per annum-5%
time period-3years find simple interest and amount​

Answer 1

Answer:

SI = 60

Amount = 460

Step-by-step explanation:

Given,

• P = 400
• R = 5%/year
• T = 3years

To find,

• Simple interest,SI = ?
• Amount,A = ?

We know,

• SI = PTR/100

Let's find the SI first and then the total amount :-

• SI = 400 x 5 x 3/100
• SI = 4 x 5 x 3
• SI = 60

Amount = Principal + SI

• A = 400 + 60
• A = 460
