Solutions:

Ans.1(5) Required average =

= 1642.331642
Ans.2(5) Required number = Total number of worker – Total number of females Z= 42500 – 9854 = 32646
Ans.3(4) Required difference = 32646 – 9854 = 22792
Ans.4(3) Number of female working in sport industry
=
Total number of female working in all industry
= 9854
Required % =

Ans.5(2) Number of female working in Chemical Industry
=
Number of males working in Sport Industry = 5355
Required ratio = 2000:5355 = 400:1071
Ans.6(2) Required average = ((16+13+17+16+19+25)×1000)/6
106000/6 = 17666.67
Ans.7(5) Required ratio ((42+36))/((19+17+19)) = 78/55 = 78:55
Ans.8(3) Required difference
= [(17+20+24)-(13+17+19)] ×1000
[61-49] ×1000 = 12000
Ans.9(4) Required% = (( 17+19+19+20+17+24))/((42+38+44+36+29+41))×100
= (116×100)/230 = 50.43% = 50.5%
Ans.10(1) Required% = ((38+29)-(16+25))/((16+25))×100
= (67-41)/41×100 = 63.41% = 63.5%
