Answer:
i) no. of students like none of subject = 5
total no. of students= 69
=> no. of students like at least one subject= 60-5
= 55
ii) no. of students like math only = 15
no. of students like science only = 20
total no. of students like only one subject= 35
no. of students like none subject = 5
=> no of students like both the subjects = 60-(35+5) =20
(iii) no. of students like math= 15+ 20
= 35 ( because 15 like math only and 20 like both)
(iv) no. of students like science= 20+20
= 40 ( because 20 like science only and 20 like both )
