Answers:
1)b 2)d 3)c 4)e 5)c 6)e 7)c 8)d 9)b 10)a
1).Total expenditure of School TVS
= 1000000 × 95 / 100 = `950000 = `9.5 lakh
Expenditure on teachers of School AKT
= 1000000 × 30 / 100 = `300000 = `3 lakh
Expenditure on non-teaching staff of School TVS
= 950000 × 20 / 100 = `190000 = `1.9 lakh
Required difference = (3 lakh – 1.9 lakh)
= `1.1 lakh
Answer: b)
2).Given total expenditure of School AKT = `10 lakh
Total expenditure of School TVS
= 1000000 × 100 / 80 = `1250000 = 12.5 lakh
Expenditure of School TVS on tour
1250000 × 12 / 100 = 150000
Expenditure of School AKT on tour
= 1000000 × 100 / 10 = `1 lakh
Required ratio = 150000: 100000 = 3 : 2
Answer: d)
3).Salary of all the teachers in School AKT
= 1000000 × 30 / 100 = `300000
Number of new teachers = 60 × 30 / 100 = 18
Number of old teachers = (60 – 18) = 42
Let the salary of an old teacher be `x.
Salary of a new teacher = 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 teacher
= 6315.78 × 3/5 = 3789.47
Answer: c)
4).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%
Expenditure reduces by (100 – 59 =) 41%
Answer: e)
5).In School TVS, 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
= 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: c)
6).(176)2 – (123)2 + (14)2
= 30976 – 15129 + 196 = 16043
Answer: e)
7).√41616 + 472 = (?)2
or, 204 + 472 = (?)2
or, 676 = (?)2
Answer: c)
8).? ÷ 10 = (16)2 – 16
or, ? ÷ 10 = 256 – 16
or, ? = 240 / 10 = 24
Answer: d)
9).182 × 93 + 5 × 127 – 42 × 37
= 16926 + 635 – 1554 = 16007
Answer: b)
10).√1444 –√784 + √2304 = ?
or, ? = 38 – 28 + 48 = 58
