Answers:
Solution:
1).Total number of employees in Company N = 700
Percentage of Science graduate employees = [100 โ (31 + 40)] = 29%
Now, the percentage difference between Arts graduate employees and Science graduate employees =(40 โ 29)% = 11%
11% of 700 = 77
Difference = 77
Answer: c)
2).The percentage of Arts graduate employees in Company Q = (100 – 35 โ 50)% = 15%
Now, the percentage of Arts graduate employees and Commerce graduate employees = 50 + 15 = 65%
Average of Commerce and Arts graduate employees = 312
The total number of employees in Commerce and Arts = 2 ร 312
Let the total employees in Company Q be x.
Then, 65% of x = 2 ร312
x = (2 ร 312 ร 100) / 65 = 960
Answer: b)
3).The percentage of Commerce graduate employees and Arts graduate employees in Company M = (100 – 32)% = 68%
Now, the percentage of Arts graduate employees = (68 ร 7) / 17 = 28%
The percentage of Commerce graduate employees = (68 ร 10) / 17 = 40%
The number of Arts graduate employees in Company M = (1050 ร 28) / 100 = 294
Answer: a)
4).The number of employees in Company N in December 2012 = 700
The number of employees in Company N in December 2013 = (700 ร 120) / 100 = 840
Number of Science graduate employees in Company N in December 2013 = (20 ร 840) / 100 = 168
Answer: e)
5).The percentage of Arts employees in Company O = (100 โ 30 – 30) = 40%
The percentage different between Arts graduate employees in Company O and P = (40 – 20) = 20%
Now, let the number of employees in Company O be x.
Then, x ร 20% = 180
x = (180 ร 100) / 20 = 900
Answer: d)
6).Reqd average = (120 + 140 + 180 + 240) / 4 = (680 / 4) = 170
Answer: d)
7).The number of watches sold in Town Y in April = 210
The number of watches sold in Town X in April = 150
Reqd % = [(210 – 150) / 150] ร 100 = (60 / 150) ร 100 = 40%
Answer: b)
8).Reqd % increase = [(230 – 120) / 120] ร 100 = (110 / 120) ร 100
= (110 ร 5) / 6 = 275 / 3 = 91 2/3%
Answer: d)
9).The number of watches sold in Town X in July = (180 ร 110) / 100 = 198
The number of watches sold in Town X in January = 120
Reqd ratio = (198 / 120) = (33 / 20) = 33 : 20
Answer: e)
10).Reqd difference = (240 + 180) โ (180 + 150) = 420 โ 330 = 90
Answer: b)
