Detailed Solution

Given,
Total number of students in the class = 40
(1) The total number of students like to study English are 1/5 of 40.
So, number of student who like to study English

= \frac{1}{5} \times 40

= 8 students

(2) Now, 2/5 of total student like the mathematics. So, total number of such students,

= \frac{2 \times 40}{5}

= \frac{80}{5}

= 16 Students

Sum of students who like English and who like Mathematics

= 8 + 16 = 24

Therefore, total students who like Science

= 40 - 24

= 16 Students

Option 1 is correct.
