Question

The formula of amount is ​

Answer 1

Answer:

A = Total Accrued Amount (principal + interest) P = Principal Amount. I = Interest Amount. r = Rate of Interest per year in decimal; r = R/100.

Example:

Question: Calculate the Simple Interest if the principal amount is Rs. 2000, the time period is 1 year and the rate is 10%. Also, calculate the total amount at the end of 1 year.

Solution:

According to the formula of simple interest we have,

S.I. = [(Principal (P) × Time (T) × Rate (r)) / 100]

So, from the above values,

S.I. = [(2000 × 1 × 10)] / 100

= 20000/100

=200

So, the simple interest at the end of 1 year will be Rs. 200.

For the amount after 1 year,

A = P + S.I.

So, A = 2000+200 = 2200

Hence, the total amount at the end of the given tenure (i.e. 1 year) will be Rs. 2200.

Answer 2

Answer:

The formula of amount is P+S.I.
