SOLUTION

→ Students passed only in Mathematics = Total number of students - (Students passed in English + Students passed in both English and  Mathematics + Students ailed in both English and Mathematics)

→ Students passed only in Mathematics = 70 - (43 + 15 + 10)

→ Students passed only in Mathematics = 70 - 68

→ Students passed only in Mathematics = 2

Therefore, only 2 students passed in mathematics.
