Answer 1

let say hindi H and english E
H=510 E=360
510+360=870 but we have 760 people and 870 - 760=110 this mean 110 people know both of these..
510-110=400 this is numbers of people knows only hindi
360-110=250 knows only english

Answer 5

as far as i understand, 4/15 absent and 11/15 present
brought raincoats number is 1/2 of 11/15 , it is 11/30 of class
then 4/15=8/30 absent and 11/30 brought raincoat
multply these 8/30+11/30=19/30
90*(19/30)=57 90-57=33 this is didnt brings raincoat's number ;)
