Find the simple interest and the amount on Rs. 4,000 at the rate of 8% per annum for 146 days?
Hint:
Find the simple interest and then add it with the principal amount to get the total amount.
The correct answer is: 4128 Rupees.
Complete step by step solution:
We calculate simple interest by the formula,
…(i)
where P is Principal amount, T is number of years and R is rate of interest
Let the sum of money P = 4000 Rs
Here, we have 
years, R = 8% and P = 4000
On substituting the known values in (i), we get 
We have SI = 128 Rupees.
We know the formula for total amount = A = P + SI…(ii)
where is the total amount, is the principal amount and is simple interest.
On substituting the known values in (ii), we get A = 4000 + 128 = 4128
Hence the simple interest after 146 days = 128 Rupees.
And total amount to be paid after 146 days = Rupees.
