town A is dark coloured one.. count the total percentage of the dark coloured squares..  then look at the X axis to find the number of children with less than 5 teeth decayed.. so its 4 until 1.. then calculate the percentag

total numnber of tooth decayed less than 5 divided by total number of tooth decayed multiplied by 100%
