What interest rate per annum if a fund paying its clients if the third to the last payment of a depositor became php 1,039.90 from an initial savings payment of php 1,000.00?

The rate of interest per annum is 1.3%.

Step-by-step explanation:

Given  Principal P = $1000

time period n = 3

Amount A = $1039.90 ≈ $1040

To find rate (r) of interest per annum

We know that :

⇒  interest rate per annum = 1.3%.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
