Question

S.I and the amount on Rs. 4000 at a rate of interest 5 % for 6 months.​

Answer 1

Answer:

s.i=p x r x t/100

time=6/12=1/2

s.i =4000 × 5 ×1/2 ÷100

s.i=100

Answer 2

Answer:

Simple Interest = $100 ; Amount = $4100

Step-by-step explanation:

$Simple Interest = \frac{Principle * Time * Rate }{100}$

To find the Simple Interest of the principle, we need to get the product of the 'Principle' , 'Time' & 'Rate' with the quotient of 100...

Principle = $4000 (assume $ as Rupees)

Time = 6 months ( = $\frac{1}{2}$ year)

Rate = 5%....

Simple Interest = $\frac{4000 * 0.5 * 5}{100}$

After cancellations and multiplications, you'll get;

Simple Interest = $100..

Now, to find the amount, we need to add up the Simple Interest with the Principle...

$Amount = Simple Interest + Principle$

Amount = $100 + $4000

Amount = $4100....
