Answer:
The compound interest is Rs8275
Step-by-step explanation:
The rule of the compound interest is A = P
, where
- r is the interest rate in decimal
- n is the number of periods
The interest I = A - P
∵ The amount of investment is Rs25000 for 3 years
∴ P = 25000
∴ t = 3
∵ The rate of interest is 10% per annum, compounded annually
∴ r = 10% = 10 ÷ 100 = 0.1
∴ n = 1 ⇒ compounded annually
→ Substitute these value in the 1st rule above to find the new amount
∵ A = 25000
∴ A = 25000
∴ A = Rs33275
→ Use the 2nd rule above to find the interest
∵ I = 33275 - 25000
∴ I = 8275
∴ The compound interest is Rs8275
Answer:
The best time is 56.81 seconds
Average leg time is 58.3825 seconds
Step-by-step explanation:
Here, we want to start by stating the team’s best time for the race
The team’s best time for the race is the smallest time spent on a lap
From the times given, the best time is 56.81 seconds
Now, we want to calculate the average time
We simply add up all these and divide by count
Mathematically, that will be;
(56.81 + 59.22 + 57.39 + 60.11)/4 = 58.3825 seconds
