उत्तर

12, 24, 24, 12, 30 and 12

∴ Mean = `(12+24+24+12+30+12)/6`

= `114/6=19`

Numbers are 12, 24, 24, 12, 30 and 12

Mostly repeated term = 12

∴ Mode = 12

Now, Arranging the numbers in ascending order = 12, 12, 12, 24, 24, 30

Here, number of terms 6 which is even

∴ Median = `1/2{"n"/2"th term"+("n"/2+1)"th term"}`

= `1/2{6/2"th term"+(6/2+1)"th term"}`

= `1/2` {3th term + 4th term}

= `1/2` {12 + 24}

= `1/2xx36`

= 18

∴ Median = 18
