Answer Key with Explanation:
1). Female voted in Kerala = 25000 × 90/100 =22500
Female voted in Manipur = 50000 × 72/100 = 36000
Female voted in Punjab = 72000 × 50/100 = 36000
Total = 94500
Male voted in Kerala = 40000 × 75/100 = 30000
Male voted in Manipur = 48000 × 70/100 = 33600
Male voted in Punjab = 60000 × 56/100 = 33600
Total = 97200
Required per cent = (97200 – 94500)/ 97200 × 100
= 2700/97200 × 100
≈ 3%
Answer is: e)
Answer is: e)
2). Female voted in Goa = 64000 × 75/100 = 48000
Female voted in Kerala = 25000 × 90/100 = 22500
Female voted in Punjab = 72000 × 50/100 = 36000
Total = 48000 +22500 + 36000 = 106500
Male voted in Goa = 70000 × 80/100 = 56000
Male voted in Manipur = 48000 × 70/100 = 33600
Total = 56000 + 33600 = 89600
Required per cent = 106500 / 89600 × 100
Answer is: e)
3). Total Females voted = 64000 × 0.75 + 50000 × 0.72 + 72000 × 0.5 + 80000 × 0.65 + 72000 × 0.48 + 25000 × 0.9
= 48000 + 36000 + 36000 + 52000 + 34560 + 22500 = 229060
Total Males not voted = 70000 × 0.2 + 48000 × 0.3 + 60000 × 0.44 + 56000 × 0.3 + 75000 × 0.55 + 40000 × 0.25
= 14000 + 14400 + 26400 + 16800 + 41250 + 10000 = 122850
Difference = 229060 – 122850
Answer is: a)
4). Male voted in Goa = 70000 × 0.80 = 56000
Male voted in Manipur = 48000 × 0.70 = 33600
Male voted in Uttarakhand = 56000 × 0.70 = 39200
Male voted in Uttar Pradesh = 75000 × 0.45 = 33750
Male voted in Kerala = 40000 × 0.75 = 30000
Male voted in Punjab = 60000 × 0.56 = 33600
Male voted in Punjab and Manipur are same
Females voted in Goa = 64000 × 0.75 = 48000
Females voted in Manipur = 50000 × 0.72 = 36000
Females voted in Uttarakhand = 80000 × 0.65 = 52000
Females voted in Uttar Pradesh = 72000 × 0.48 = 34560
Females voted in Kerala = 25000 × 0.90 = 22500
Females voted in Punjab = 72000 × 0.5 = 36000
Females voted in Punjab and Manipur are same
Answer is: b)
5). Total Males = 70 + 48 + 60 + 56 + 75 + 40 = 349 thousand
Total Male voters = 70 × 0.8 + 48 × 0.7 + 60 × 0.56 + 56 × 0.7 + 75 × 0.45 + 40 × 0.75
= 56 + 33.6 + 33.6 + 39.2 + 33.75 + 30
= 226.15 thousand
Difference = 349 - 226.15
= 122.85 thousand
Answer is: b)
6). Salary of all the professors in IIT College
= 1000000 × 30 / 100 = 300000
Number of new professors = 60 × 30 / 100 = 18
Number of old professors (including principal) = (60 – 18) = 42
Let the salary of an old professor be x.
Salary of a new professor = x × 60 / 100 = 3x / 5
Now, salary of Principal = 11x / 10
So, x × 41 + 11x / 10 + 3x × 18 / 5 = 300000
or,( 410x + 11x + 54x) / 10 = 300000
or, 475x = 300000 × 10
x = 300000 × 10 / 475 = 6315.78
Salary of a new professor
= 6315.78 × 3/5
Answer is: c)
7). Total expenditure of IIS College
= 1000000 × 95 / 100 = 950000 = 9.5 lakh
Expenditure on professors of IIS College
= 950000 × 25 / 100 = 237500 = 2.375 lakh
Expenditure on non-teaching staff of IIS College
= 950000 × 20 / 100 = 190000 = 1.9 lakh
Required difference = (2.375 lakh – 1.9 lakh)
= 0.475 lakh
Answer is: b)
8). Given total expenditure of IIT College = 10 lakh
Total expenditure of IIS College
= 1000000 × 100 / 80 = 1250000 = 12.5 lakh
Expenditure of IIS College on tour
= 1250000 × 12 / 100 = 150000 = 1.5 lakh
Expenditure of IIT College on tour
= 1000000 × 10 / 100 = 1 lakh
Required ratio = 150000: 100000
Answer is: d)
9). In summer vacation there is no expenditure on sports, tour, electricity and lab.
The remaining expenditure of IIT = expenditure on professor + non-teaching staff + others
= 30 + 15 + 14 = 59%
Expenditure reduces by (100 – 59 =) 41%
The remaining expenditure of IIS = expenditure on professor + non-teaching staff + others
= 25 + 20 + 15 = 60%
Expenditure reduces by (100 – 60 =) 40%
Difference = 41% - 40% = 1%
Answer is: e)
10). In IIS College, the expenditure on non- teaching staff
= 12 × 20/100 = 2.4 lakh
Expenditure on each non-teaching staff
= 240000 / 50 = 4800
After removing 30% the number of non-teaching staff, the no. of non-teaching staff
= 50 × 70/100 = 35
Salary of 35 non-teaching staff = 35 × 4800
= 168000 = 1.68 lakh
Reduction in expenditure = 2.4 lakh – 1.68 lakh = 0.72 lakh = 72000
Percentage reduction in total expenditure
= 72000 / 1200000 × 100 = 6%
Answer is: c)
