Solutions:
1. (e) Male Engineers + Male Designers 40% of (18% of 10500)
+ 65% of (16% of 10500)
+ 65% of (16% of 10500)
Female Engineers + Female Designers = 60% of (18% of 10500)
+ 35% of (16% of 10500)
+ 35% of (16% of 10500)
Required ratio = (40 × 18) + (65 × 16) : (60 × 18 + 35 × 16)
= (720 + 1040) : (1080 + 560) = 1760 : 1640 = 44 : 41
= (720 + 1040) : (1080 + 560) = 1760 : 1640 = 44 : 41
2. (c) Required % = 19/21 ×
100 » 90%
100 » 90%
3. (b) % of female professionals = [20% of 21% + 60% of 18%
+ 40% of 11% + 80% of 15% + 40% of 19% + 35% of 16%]
+ 40% of 11% + 80% of 15% + 40% of 19% + 35% of 16%]
= 1/100 [420 + 1080 + 440 +1200 + 760
+ 560]%
+ 560]%
= 4460/100 % = 44.6%
So, % of male
professionals = 100% – 44.6% = 55.4%
professionals = 100% – 44.6% = 55.4%
So, Required diff = (55.4 – 44.6)% of 10500
= 10.8% of 10500 = 10.8 × 105 = 1134
4. (d) Required %
