If there are 200 boys in class in 2019 and number of girls who didn’t participate in 2019 is 5 more than no. of students who didn’t participate in 2017 then what is the ratio of no. of girls who participated in 2019 to total students who participated in 2018?
5 : 9
Cannot be determined
20 : 27
5 : 8
5 : 6
no. of boys who didn’t participate in 2019 = 110
No. of girls who didn’t participate in 2019 = 5 + 25/100×180 = 50
Total students in 2019 = 160/40×100=400
No. of girls who participated in 2019 = 200 – 50 = 150
Required ratio = 150 : (90/100×300) = 5 : 9
