Correct Answer - Option 1 : 22
Given:
Total number of students = 550
Number of males = 40%
Calculations:
Total number of students = 550
Number of males = 40%
⇒ Number of males = (40/100) × 550 = 220
Number of females = (550 - 220) = 330
Now, Males who participated in dancing = 10% of 220
⇒ Males who participated in dancing = (10/100) × 220 = 22
Now, Females who participated in dancing = 33.33% of 330
⇒ Females who participated in dancing = (1/3) × 330 = 110
Total number of students who participated in dancing = (22 + 110)
⇒ Total number of students who participated in dancing = 132
Students participated in anchoring = 16.67% of 132
⇒ Students participated in anchoring = (1/6) × 132 = 22
∴ The number of students who participated in anchoring is 22.
