its not wrong. its right ..
make a pair .. as per question..

19+1=20 .that means if we choose 19 students then there will be 1 teacher in that group. total =20

now to make 1400 equivalent to the 20 ..divide it by 20=70 answer.

Dear Student,
Its so obvious that a team will have = 19 Students + 01 teachers = 20 People, so 1400 will be divided by 20 which will be equal to 70, so there are 70 team, each team consisting of 01 teacher, hence 70 teachers are there. Hope you got it.
