What was the total number of children who attended the Swimming and Athletics, and Music classes in June 2016, if the number of children increased by 20% in June 2017 for these classes as compared to June 2016?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 190.
Swimming and Athletics + Music classes = 22% + 16% = 38%
Number of children who attended the Swimming, Athletics, and Music classes in 2017 = (38/100) × 600 = 228
Total children of Swimming, Athletics, and Music classes in 2016 = 228 × (100/120) = 190
