Question

find si on rs 5600 at 6 2/3% per annum for a period of 9 month​

Answer 1

Answer:Rs.280

Step-by-step explanation:

Principal=5600

Rate=6*2/3%=20/3%

Time=9mths.=9/12yr.

Simple interest

=5600×20×9/100×3×12

=280

Answer 2

Given,

Principal amount (P) = Rs. 5600

Rate (R) = 6 2/3% per annum

Time (T) = 9 months

To find,

The simple interest on the given principal amount and rate for 9 months.

Solution,

The simple interest on Rs. 5600 at 6 2/3% per annum for 9-months will be Rs. 280.

We can easily solve this problem by following the given steps.

Now, we know that the formula to find the simple interest is the principal amount (P) × Rate (R) × Time (T)/100.

Simple interest = P×R×T/100

According to the question,

Principal Amount (P) = Rs. 5600

Rate (R) = 6 2/3% per annum

Time (T) = 9 months

Now, we will first convert the rate into a complete fraction.

Rate (R) = 6 2/3%

R = (6×3+2)/3 %

R = 20/3 %

Now, converting the time into years,

T = 9 months

( We know that in a year there are 12 months.)

T = 9/12 year

Now, converting it into the simplest form

T = 3/4 year

Simple interest = P×R×T/100

SI = 5600×20×3/100×3×4

SI = 56×20×3/3×4

SI = 56×20/4

SI = 56×5

SI = Rs. 280

(Note that the total amount after 9 months will be the sum of the principal amount and the simple interest.)

Hence, the simple interest on Rs. 5600 at 6 2/3% per annum for 9-months is Rs. 280.
