Answer» The average number of boys in 8 classes of a school is 42. So, total number of boys = 8 × 42 = 336 If in three of the classes, 4 boys are replaced by GIRLS, the number of boys will decrease by 12, and number of girls will increase by 12. Now, average number of girls BECOMES 47.5. ⇒ Total number of girls = 8 × 47.5 = 380 ⇒ Total number of students = (336 – 12) + 380 = 704 |
