Step-by-step explanation:
No. of total students= 40
No. of students who like Mathematics= 2/4 × 40= 20 students
No. of students who like English= 1/5 × 40= 8 students
No. of students who like Science= x students
Total students= No. of (Mathematics+English+Science)
40 students= 20 students+8 students+x students
40 students= 28 students+x students
40 students-28 students= x
12 students= x
No. of students who like Science= 12 students
