Question

pls find the answer with steps clearly one by one

Answer 1

given,
total no. of students=40
1/5 of total students study eng
so, 1/5 of 40 =8
and
2/5 of total students study maths
so, 2/5 of 40=16
now,
the questions are
A)no. of students like to study english= 8..........(from above)
B)no. of students like to study maths=16...........(from above)
C)fraction of total no. of students like to study science:
no. of students who like sci = (total no. of students)-(no. of students who like maths+no. of students who like eng)
so,(40)-(8+16)
=40-24
=16
fraction = no. of students who like sci/total no. of students
therefore, 16/40
=2/5
so, fraction of total no. of students who like to study science =2/5
