The weekly wages (in Rs) of 30 workers in a factory are given:830, 835, 890, 810, 835, 836, 869, 845,898, 890, 820, 860, 832, 833, 855, 845, 804, 808, 812, 840, 885, 835, 835, 836, 878,840, 868, 890, 806, 840 Marks a frequency table with intervals as 800-810, 810-820 and so on, using tally marks Also, draw a histogram and answer the following questions:
(i) Which group has the maximum number of workers?
(ii) How many workers earn Rs 850 and more?
(iii) How many workers earn less than Rs 850?

(iii) How many workers earn less than Rs 850?
The frequency table will be as given below:

We represent wages (in Rs) along x-axis and number of workers along y-axis. Taking suitable intervals, we construct rectangle as shown in the figure. This is the required histogram.
(i) Maximum workers are in the wage group 830-840.
(ii) Number of workers getting Rs 850 and more are 1+3+1+14=10.
(iii) Number of workers getting less than Rs 850 are 3+2+1+9+5=20
