Important for :
1
What is the difference between the total population of city A and that of the city D?
» Explain it
B
In City A, the number of child labours = 24% of 4800 = 1152 = 0.4% of the total population

 The total population = 1152 × 100 = 288000 0.4

In City B, the number of child labours = 18% of 4800 = 18 × 48 = 0.2% of the total population

 The total population = 18 × 48 × 100 = 432000 0.2

In City C, the number of child labours = 20% of 4800 = 20 × 48 = 0.5% of the total population

 The total population = 20 × 48 × 100 = 192000 0.5

In City D, the number of child labours = 16% of 4800 = 16 × 48 = 0.3% of the total population

 The total population = 16 × 48 × 100 = 256000 0.3

In City E, the number of child labours = 22% of 4800 = 22 × 48 = 0.24% of the total population

 The total population = 22 × 48 × 100 = 440000 0.24

The Required difference = 288000 – 256000 = 32000

Hence, option B is correct.
2
Find the sum of the total number of people in the cities B and D together who are not child labour?
» Explain it
A
The total population of city B and D together = 432000 + 256000 = 688000

the total number of people in the cities B and D together who are not child labour = 688000 – (18 × 48 + 16 × 48) = 688000 – (864 + 768) = 688000 – 1632 = 686368

Hence, option A is correct.

3
What is the ratio of the total population of city C to that of the city E?
» Explain it
C
The required ratio = 192000 : 440000 = 24 : 55

Hence, option C is correct.

The number of child labours in the city A is what percentage of the total population of the city C?
» Explain it
C
The number of child labours in the city A = 1152

the total population of the city C = 192000

 The reqd. % = 1152 × 100 = 0.6% 192000

» Explain it
C
288000 + 432000 + 192000 + 256000 + 440000 = 1608000
