In a class of ________ students, number of girls in the class is 6 more than the number of boys in the class. The average weight of the all the students in the class is 42.25 Kg. Average weight of the boys is __________ Kg and average weight of the girls is 40 Kg. Which of the following option satisfies the given condition?

Let boys = b, girls = b+6. Check option C: b=27, g=33, total=60. Total weight = 60 × 42.25 = 2535. Boys' weight = 27 × 45 = 1215. Girls' weight = 33 × 40 = 1320. Sum = 1215 + 1320 = 2535. Correct. Check other options: A (50, 42): b=22, g=28. Boys' weight = 22×42 = 924, girls' weight = 28×40 = 1120. Total weight = 2044, but 50×42.25 = 2112. Incorrect. B (40, 45): b=17, g=23. Total = 2110 vs 40×42.25 = 1690. Incorrect. D (46, 42): b=20, g=26. Total = 2064 vs 46×42.25 = 1943.5. Only C works.
