उत्तर

Weekly wages
(Rupees)
Class mark
(xi)
No. of workers
(fi)
fixi
0 – 2000 1000 15 15000
2000 – 4000 \[\boxed{3000}\] 35 105000
4000 – 6000 5000 50 250000
6000 – 8000 7000 20 140000
    N = 120 Σfixi = \[\boxed{510000}\]

Mean = `(sumf_ix_i)/(sumf_i)`

= \[\frac{\boxed{510000}}{120}\]

= \[\boxed{4250}\]
