What is the total number of children in areas P and Q together?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 8000.
Number of children in area P = 20% of 10000 = 2000
Number of children in area Q = 30% of 20000 = 6000
Hence,
Total number of children in P and Q = 2000 + 6000 = 8000
