Answer = 3
Mean = Sum of Observations ÷ Number of Observations
Mean = (10+20+30+40+50) ÷ 5 ×10
(I got 10 from the question as it is written that each value must be divided by 10)
Mean = 150 ÷ 50
Mean = 3

(if divide by 10 or any other number is not given in the questionthen only use the mean formula and do it.)
