Answer:
number of Students who like to study english=8 students
number of Students who like to study science=16 students
Step-by-step explanation:
a)to find number of students who like to study English:
total students=40
students who like to study english=1/5 (in fractions)
∵1/5×40=8 students
∴8 students like to study english
b)to find number of students who like to study science, we require the number of students who like to study mathematics
∴number of students who like to study maths:
2/5×40=16 students
now to find number of students who like to study science:
∵40-(16+8)=16 students
∴16 students like to study science
