Question

2) Manu borrowed rs.8500 at the rate of 5% interest per annum for 150 days. Find the interest and amount he paid.
​

Answer 1

Answer:

Amount to be paid=principal amount+Simple interest

Simple interest=P×R×T100P×R×T100 where P is the principal amount ,T is time and R is the rate of the interest.

Simple interest=10,000×15×2100=300010,000×15×2100=3000

Amount to be paid=10,000+3000=Rs.13000

Answer 2

Given:

Money Borrowed = Rs. 8500

Rate = 5%

Time = 150 days

To find:

The interest and amount he paid.

Solution:

Time = 150 days

= 150/365 ( In one year there are 365 days)

Using the formula of Simple Interest -

SI = PRT/100

= (8500 × 5 × 150/365)/100

= (8500 × 150/73)/100

= 174.6

Amount = SI + P

= 8500 + 174.6

= 8674.6

Answer: The interest is Rs. 174.6 and the amount to be paid is Rs. 8674.6
