74. A book has 'n' number of pages. At exact n/2 number of page, third paragraph fourth sentence, fourth word states, “m hr” and at exact n/3
number of page, first paragraph, first sentence fourth word states,
“svdmsx” and finally at exact n number of page, the last paragraph,
first sentence, sixth word states “696205514”. What is the total
number of pages? (Hint: No. of page is encoded in these words)
A) 6962055145
B) 15
C) 20
D) 345

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.
