Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 30.
Calculations:
The total number of students who opted for Yoga and Painting taken together = 300 × (18 + 12)%
⇒ 30% of 300 = 90
The total number of children who opted for Music and Dance taken together = 300 × (24 + 16)%
⇒ 40% of 300 = 120
Required difference = 120 - 90 = 30
