Find the solution of ×\2-1/5=×\3+1/4 please help me with this

Step-by-step explanation:

Assuming that the beginning equation is

First, we should find the common denominator of each of fractions. For all of these denominators, 60 is the smallest common denominator

Now, we can multiply each side by 60, which will remove the fractions

Now we can add 12 to each side

Now subtract 20x from each side

And lastly, divide each side by 10

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.
