1). Answer: 3)
Total number of bikes sold by all states together = 120000 (0.3 × 0.9 + 0.2 × 0.8 + 0.15 x 0.75 + 0.15 x 0.85 + 0.2 x 0.7) = 120000 (0.27 + 0.16 + 0.1125 + 0.1275 + 0.14) = 120000 × (0.81) = 1200 x 81 = 97200
3). Answer: 2)
Reqd. difference = 1.2 lakh (15% × 75% + 20% × 80% - 15% x 85% - 30% × 90)
= 1.2 lakh (16% - 27% - 15% (85 - 75)%) = 1.2 lakh × (- 11% - 1.5%) = 1.2 lakh (12.5%) {Taking mode value)
= 120000 / 8 = 15000
4). Answer: 5)
The number of unsold bikes in Andhra Pradesh = 120000 x 15/100 x 25/100 = 4500; and
Maharashtra = 120000 x 20/100 × 20/100 = 4800
The number of unsold bikes in all five states = 120000 - 97200 = 22800
(Using solution of Q (1)
Reqd. % = (4500 + 4800) / 22800 x 100 = 9300 / 22800 x 100 = 40.8%
5). Answer: 5)
Total profit earned by a company in Haryana = (Profit on one bike) x Number of bikes
= (80000 - 75000) x 1.2 lakh x 30% x 90% = 5000 x 32400 = 162000000 = 16.2 cr
6). Answer: 2)
Total expenditure of School B = 1000000 x 95/100 = Rs. 950000 = Rs. 9.5 lakh.
Therefore, Expenditure on teachers of School A = 1000000 x 30/100 = Rs. 300000 lakh = Rs. 3 lakh
Expenditure on non-teaching staff of School à B = 950000 x 20/100 = Rs.190000 = Rs. 1.9 lakh
Therefore, Reqd. difference = (3 lakh – 1.9 lakh) = Rs. 1.1 lakh
7). Answer: 4)
Given total expenditure of School A = Rs. 10 lakh
Total expenditure of School B = 1000000 x 100 / 80 = Rs. 1250000 = Rs. 12.5 lakh
Therefore, Expenditure of School B on tour =1250000 x 12 / 100 = 150000 = 1.5 lakh
Expenditure of School A on tour = 1000000 x 10 / 100 = Rs. l lakh
Therefore, Reqd. ratio = 150000: 100000 = 3: 2
8). Answer: 4)
Salary of all the teachers in School A = 1000000 x 30 / 100 = Rs. 300000
Number of new teachers = 60 x 30 / 100 = 18
Number of old teachers = (60 –18) = 42
Let the salary of an old teacher be Rs. x.
Salary of a new teacher = x × 60 / 100 = 3x / 5
Now, salary of principal =Rs. 11x / 10
So, x × 42 + 11x/10 + 3x × 18 / 5 = 300000
(420x +11x+ 54x) / 10 = 300000
or, 485x= 300000 x 10
x = 300000 x10 / 485 à x = Rs. 6185.56
Salary of a new teacher = 6185.56 × 3 / 5 = 3711.33
9). Answer: 5)
In summer vacation there is no expenditure on sports, tour, electricity and lab.
The remaining expenditure = expenditure on teacher + non-teaching staff + others
= 30 + 15 + 14 = 59%
Therefore, Expenditure reduces by (100 – 59 =) 41%
10). Answer: 3)
In School B, the expenditure on non-teaching staff = 12 x 20/100 = 2.4 lakh
Expenditure on each non-teaching staff = 240000 / 50 = Rs. 4800
After removing 30% the number of non-teaching staff= 50 x 70 / 100 = 35
Salary of 35 non-teaching staff = 35 x 4800 = Rs.168000 =1.68 lakh
Therefore, Reduction in expenditure = 2.4 lakh – 1.68 lakh = 0.72 lakh = Rs. 72000
Therefore, Percentage reduction in total expenditure = 72000 /1200000 x 100 = 6%
