Puzzle 1 .

total number of students = 28.
maths and history taken by 6 students .

therefore remaining studensts = 28 - 6
                  = 22.

students taking history and english are even and non-zero and are equal to five times the students taking history , english and mathematics.

 students with history and english = 2 (IT cannot be 4 since 4 + 5*4 IS > 22(the number of remaining students) )
 students with history , english , maths = 5*2
                    = 10

In case of Number of history and english students =2 ,the number of mathematics students = (22 - 2- 5*2 )/2
                         = (22 - 2 -10)
                        = 5
Note the division is because number of students    with maths only = number of students taking maths and english .
