Salma Bruce · Answer 1

0.75 of 60 = 45 students and 35% of 60 = 21 students, so it means there are 60-21=39 students with only maths, 45-39=6 students have both maths and science, 60-45=15 students with only science

Audrey Fox · Answer 2

0,75⇔75% (m)

35% (s)

75%+35%=110%

110%-100%=10% (m+s)

75%-10%=65% (only m)

60-100%

(?) - 65%

65*60:100=39 (stud.)
