The interest paid is Rs 10000
The rate of interest is 20%
Step-by-step explanation:
Step 1 :
Amount borrowed by Mr. Satyal = Rs 50000
Amount repaid = Rs 60000
Interest is charged on the principal amount and the amount repaid will be the sum of the interest paid plus the principal amount
Hence the interest paid is 60000 - 50000 = Rs 10000
Step 2:
The rate of interest is calculated as follows :
Divide the interest calculated by the principal amount and is expressed as percentage.
Hence the interest rate =
× 100 = 20%
Step 3 :
The interest paid is Rs 10000
The interest rate is 20%
Replace the x in the equation with the given value of x and you will find that the 3rd equation is corret.
F(X) = 4(1/2)^X
4(1/2)^-2 = 4 * 4 = 16
3/4 divided by 4 is 0.1875
Since there are 5 possible outcomes and 3 is only one of the outcomes, the probability would be 1/5 or 20%
