Detailed Solution:
1. Expenditure of D on food =(20/100) x 30000 = 6000
Average expenditure on food for all the six persons = 6000/1.2 = 5000
2. Total expenses on rent, education and telephone and electricity bills
= (15 + 16 + 10)/100 x30000
=12300
3. Expenses of B on clothes = (10/100) x 28000 = 2800
Expenses of F on clothes = (15/100) x 32000 = 4800
Required Percentage = (4800 – 2800)/2800 x 100% = 71.4%
4. As the monthly expenses on fuel for each of them is (5/100) x 30000 = 1500, it would be more
than 5% of their monthly expenses (less than 30000) i.e. A, B, C and E
5. Expenses on “others” for d = (22/100) x 30000 = 6600
Expenses on “others” for A = 6600 x 1.1 = 7260
Required percentage = (7260/24000) x 100 = 30.25%
6. Officers taking training in HRM = 10 + 80 + 18 + 20 = 128
7. Clerks taking training in computer skills but not in HRM = 70 +9 = 79
8. Employees taking training in financial skills but not in HRM = 87 + 21 = 108
9. Clerks taking training in financial skills = 47 + 50 + 9 + 9 = 115
10. Officers taking training in computer skills but not in financial skills = 20 + 20 = 40
Total number of officers = 200
Required percentage = (40/200) x 100 = 20%
