Solution
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
