Answers :
1). Answer: b)
Required % = [(780 – 450)/450]*100 = 73 %
2). Answer: d)
Total number of males = 780 + 600 + 1000 + 750 + 1200 + 650 = 4980
Total number of females = 1200 + 1000 + 500 + 450 + 800 + 400 = 4350
Required difference = 4980 – 4350 = 630
3). Answer: b)
Total number of females working in company A, B and C together
= > 1200 + 1000 + 500 = 2700
Total number of males working in company D, E and F together
= > 750 + 1200 + 650 = 2600
Required ratio = 2700: 2600 = 27: 26
4). Answer: c)
Total number of males of company B, C and E together
= > 600 + 1000 + 1200 = 2800
Total number of females of company A, D and F together
= > 1200 + 450 + 400 = 2050
Required % = (2800/2050)*100 = 136 %
5). Answer: b)
Total number of females in all the given companies together
= > 1200 + 1000 + 500 + 450 + 800 + 400 = 4350
Required average = 4350/6 = 725
6). Answer: b)
Total number of items sold by P all the given days together
= > 500 + 650 + 525 + 725 + 800 + 425 + 600 = 4225
Total number of items sold by Q all the given days together
= > 700 + 775 + 600 + 650 + 550 + 475 + 400 = 4150
Required percentage = (4225/4150)*100 = 101.8 % = 100 %
7). Answer: c)
The number of items sold by shop R in Wednesday and Thursday together
= (4/5)*725 + (3/4)*800
= 580 + 600 = 1180
The number of items sold by shop S in Thursday and Friday together
= (9/11)*550 + (18/19)*475
= 450 + 450 = 900
Required percentage = [(1180 – 900)/900]*100 = 31 % = 30 %
8). Answer: d)
The number of items sold by shop R in Sunday, Monday and Tuesday together
= (6/5)*500 + (12/13)*650 + (9/7)*525
= 600 + 600 + 675 = 1875
The number of items sold by shop S in Wednesday, Thursday and Friday together
= (15/13)*650 + (9/11)*550 + (18/19)*475
= 750 + 450 + 450 = 1650
Required ratio = 1875: 1650 = 25: 22
9). Answer: b)
Total number of items sold by shop R all the given days together
= > (6/5)*500 + (12/13)*650 + (9/7)*525 + (4/5)*725 + (3/4)*800 + (15/17)*425 + (2/3)*600
= > 600 + 600 + 675 + 580 + 600 + 375 + 400
= > 3830
10). Answer: c)
Total number of items sold by Q in all the given days together
= > 700 + 775 + 600 + 650 + 550 + 475 + 400 = 4150
Total number of items sold by S in all the given days together
= > (2/5)*700 + (32/31)*775 + (3/2)*600 + (15/13)*650 + (9/11)*550 + (18/19)*475 + (5/4)*400
= > 280 + 800 + 900 + 750 + 450 + 450 + 500
= > 4130
Required difference = 4150 – 4130 = 20
