Daily Income (in Rs.) 200-220 220-240 240-260 260-280 280-300
Number of workers 12 14 8 6 10
C.F (less type) 12 12 + 14 = 26 26 + 8 = 34 34 + 4 =40 40 + 10 = 50

As it is a less than type curve we will take Daily income (starting with the lower limit of each class) on the x-axis and No. workers on the y-axis.
