The number of teachers
Math: 6, English: 4, Science: 3, Hindi: 5, History: 2
Since one particular English teacher is fixed and atleast one teacher should be there of each subject.
⇒ No. ways of selection of remaining 3 teachers = (All 3 Hindi teachers) + (2 Hindi and 1 English) + (1 Hindi and 2 English)
We know that,
5C3 + 5C2 × 4C1 + 5C1 × 4C2
⇒ 10 + 10 × 4 + 5 × 6
⇒ 10 + 40 + 30
∴ Required number of ways = 80
Hence, the correct option is (B).
