1) Answer: a)
Population of age group (15 – 60) in country P = 80 – (10 + 30) = 40
80% = (Labour Force/40) * 100
Labour Force in country P = (80/100) * 40 = 32
Population of age group (15 – 60) in country Q = 100 – (15 + 25) = 60
50% = (Labour Force/60) * 100
Labour Force in country Q = (50/100) * 60 = 30
Population of age group (15 – 60) in country R = 120 – (20 + 20) = 80
75% = (Labour Force/80) * 100
Labour Force in country R = (75/100) * 80 = 60
Population of age group (15 – 60) in country S = 50 – (10 + 15) = 25
60% = (Labour Force/25) * 100
Labour Force in country S = (60/100) * 25 = 15
Population of age group (15 – 60) in country T = 80 – (20 + 30) = 30
80% = (Labour Force/50) * 100
Labour Force in country T = (80/100) * 30 = 24
Total population of country P = 80
Total employed in country P = 30% of 80 = 24
Total unemployed out of Labour Force = 30 – 24 = 8
Unemployment rate = (8/32) * 100 = 25%
2) Answer: c)
Unemployment rate = (Unemployed/Labour Force) * 100
40 = (Unemployed/30) * 100
Unemployed = 12
Employed = 30 – 12 = 18
Required ratio = 18: 15 = 6: 5
3) Answer: a)
Unemployment rate of P = (Unemployed/Labour Force) * 100
x = (Unemployed/32) * 100
Unemployed in P = 0.32x
Unemployment rate of R = (Unemployed/Labour Force) * 100
60 = (Unemployed/60) * 100
Unemployed in R = 36
According to the question:
36 – 0.32x = 15200/1000
0.32x = 20.8
x = 65
Now,
Unemployment rate in Q = (Unemployed/Labour Force) * 100
(x + 25) = (Unemployed/30) * 100
Unemployed in Q = [(65 + 25) * 30]/100
Unemployed in Q = 27
4) Answer: b)
Let unemployed population of country R and S is ‘5x’ and ‘x’ respectively.
Unemployment rate of R = (Unemployed/Labour Force) * 100
Unemployment rate of R = (5x/60) * 100
Unemployment rate of R = 25x/3
Unemployment rate of S = (Unemployed/Labour Force) * 100
Unemployment rate of S = (x/15) * 100
Unemployment rate of S = 20x/3
According to the question:
(25x/3) – (20x/3) = 15
x = 9
Sum of unemployed population (thousands) in both the countries together = 5x + x = 6x = 54
5) Answer: b)
Let unemployed population in T = ‘a’
Total population of age group (< 15) in T = 30
a = x% of 30
a = 0.3x ……… (1)
Total population of age group (< 15) in T = 30
a = (x + 18)% of 20
From equation (1):
0.3x = 0.2(x + 18)
0.3x = 0.2x + 3.6
x = 36
Unemployment rate = (a/24) * 100
= (0.3x/24) * 100
= 45%
Population of age group (15 – 60) in country P = 80 – (10 + 30) = 40
80% = (Labour Force/40) * 100
Labour Force in country P = (80/100) * 40 = 32
Population of age group (15 – 60) in country Q = 100 – (15 + 25) = 60
50% = (Labour Force/60) * 100
Labour Force in country Q = (50/100) * 60 = 30
Population of age group (15 – 60) in country R = 120 – (20 + 20) = 80
75% = (Labour Force/80) * 100
Labour Force in country R = (75/100) * 80 = 60
Population of age group (15 – 60) in country S = 50 – (10 + 15) = 25
60% = (Labour Force/25) * 100
Labour Force in country S = (60/100) * 25 = 15
Population of age group (15 – 60) in country T = 80 – (20 + 30) = 30
80% = (Labour Force/50) * 100
Labour Force in country T = (80/100) * 30 = 24
Total population of country P = 80
Total employed in country P = 30% of 80 = 24
Total unemployed out of Labour Force = 30 – 24 = 8
Unemployment rate = (8/32) * 100 = 25%
2) Answer: c)
Unemployment rate = (Unemployed/Labour Force) * 100
40 = (Unemployed/30) * 100
Unemployed = 12
Employed = 30 – 12 = 18
Required ratio = 18: 15 = 6: 5
3) Answer: a)
Unemployment rate of P = (Unemployed/Labour Force) * 100
x = (Unemployed/32) * 100
Unemployed in P = 0.32x
Unemployment rate of R = (Unemployed/Labour Force) * 100
60 = (Unemployed/60) * 100
Unemployed in R = 36
According to the question:
36 – 0.32x = 15200/1000
0.32x = 20.8
x = 65
Now,
Unemployment rate in Q = (Unemployed/Labour Force) * 100
(x + 25) = (Unemployed/30) * 100
Unemployed in Q = [(65 + 25) * 30]/100
Unemployed in Q = 27
4) Answer: b)
Let unemployed population of country R and S is ‘5x’ and ‘x’ respectively.
Unemployment rate of R = (Unemployed/Labour Force) * 100
Unemployment rate of R = (5x/60) * 100
Unemployment rate of R = 25x/3
Unemployment rate of S = (Unemployed/Labour Force) * 100
Unemployment rate of S = (x/15) * 100
Unemployment rate of S = 20x/3
According to the question:
(25x/3) – (20x/3) = 15
x = 9
Sum of unemployed population (thousands) in both the countries together = 5x + x = 6x = 54
5) Answer: b)
Let unemployed population in T = ‘a’
Total population of age group (< 15) in T = 30
a = x% of 30
a = 0.3x ……… (1)
Total population of age group (< 15) in T = 30
a = (x + 18)% of 20
From equation (1):
0.3x = 0.2(x + 18)
0.3x = 0.2x + 3.6
x = 36
Unemployment rate = (a/24) * 100
= (0.3x/24) * 100
= 45%

6) Answer: e)
Total number of students in class V = 88*4= 352
Let the number of students in section D be x
Section B= x*120/100= 6x/5
So,
x+6x/5+ 60+39= 352
11x/5= 352-99
11x/5= 253
x= 253*5/11
x= 115
Number of students in section B= 6*115/5= 138
Required ratio= 138:100= 69:50
7) Answer: c)
Let the let the number of students initially in section C be x
Now,
Number of students in section C = x+20
60/x+20 = 4/5
300= 4x+80
220= 4x
x= 55
8) Answer: d)
Total weight of all students= 50*160= 8000 kg
So,
96*x + 64(x-10) = 8000
96x + 64x – 640= 8000
160x= 8000+640
x= 8640/160
x= 54 kg
Average weight of section C = 54 -10= 44 kg
Total weight if we include weight of the teacher
= (44*64) + 44 = 2816 + 44 = 2860 kg
Required average weight= 2860/65= 44 kg
9) Answer: a)
Let the number of students in section D of class VII and VIII be x and y respectively
So,
(80+90+16+x) + (85+30+45+y) = 620
186+x+160+y = 620
x + y = 620- 346
x + y = 274
Required average = 274/2 = 137
10) Answer: e)
Number of students in section C of class X= 45*4/5= 36
Number of students in section A of class X= 36*150/100= 54
Required average= (54+50+36+100)/4 = 240/4 = 60 students
Total number of students in class V = 88*4= 352
Let the number of students in section D be x
Section B= x*120/100= 6x/5
So,
x+6x/5+ 60+39= 352
11x/5= 352-99
11x/5= 253
x= 253*5/11
x= 115
Number of students in section B= 6*115/5= 138
Required ratio= 138:100= 69:50
7) Answer: c)
Let the let the number of students initially in section C be x
Now,
Number of students in section C = x+20
60/x+20 = 4/5
300= 4x+80
220= 4x
x= 55
8) Answer: d)
Total weight of all students= 50*160= 8000 kg
So,
96*x + 64(x-10) = 8000
96x + 64x – 640= 8000
160x= 8000+640
x= 8640/160
x= 54 kg
Average weight of section C = 54 -10= 44 kg
Total weight if we include weight of the teacher

Required average weight= 2860/65= 44 kg
9) Answer: a)

x + y = 620- 346
x + y = 274
Required average = 274/2 = 137
10) Answer: e)
Number of students in section C of class X= 45*4/5= 36
Number of students in section A of class X= 36*150/100= 54
