Question : The following table represents the population of four different areas and the percentage of males, females, and children among them.
| Area | Population | Males | Females | Children |
| P | 10,000 | 40% | 40% | 20% |
| Q | 20,000 | 30% | 40% | 30% |
| R | 16,000 | 50% | 30% | 20% |
| S | 18,000 | 45% | 35% | 20% |
What is the total number of children in areas P and Q together?
Option 1: 7000
Option 2: 9000
Option 3: 6000
Option 4: 8000
Correct Answer: 8000
Solution :
The total number of children in areas P and Q together = Number of children in area P + number of children in area Q
= 20% of 10,000 + 30% of 20,000
= $\frac{20}{100}\times10000+\frac{30}{100}\times 20000$
= $2000+6000$
= $8000$
Hence, the correct answer is 8000.
