The following figure represent the no. of books issued at the counter of school library on 12 different days 75,98,102,200,610,75,80,100 ,180,270 Find the mean, mode, Median​

Answer 1

Answer:

firstly we rearrange all numbers in ascending order

then

mean=sum of all observation/ no. of observation

so rearrange no. are

75,75,80,98,100,102,180,200,270,610

mean =75+75+80+98+100+102+180+200+270+610/10

=1790/10

=179

now, mode will be 75,because it comes 2 times
