There were 330 students in a school. On the school anniversary,
56 of the girls and
34 of the boys came in pink windbreakers. The rest came in blue windbreakers. The number of boys who wore blue windbreakers was four times of the girls who wore blue windbreakers. How many students were in pink windbreakers that day?

The number of boys who came in blue windbreakers is repeated. Make the number of boys who came in blue windbreakers the same. LCM of 1 and 4 is 4.
Total number of students
= 5 u + 1 u + 12 u + 4 u
= 22 u
22 u = 330
1 u = 330 ÷ 22 = 15
Number of students in pink windbreakers
= 5 u + 12 u
= 17 u
= 17 x 15
= 255
Answer(s): 255
