The sum of two numbers is 18
and their difference is 6.
What are the two numbers
?
Larger number
Smaller number

x+y=18

x-y=6

add both equation

2x=12

x=6

y=18-6=12

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.

it would more likely be bald eagle because its has more in the box so about 75%.
