Answer / hari

a)english alone-12
b)adding all the elements we get 12+10+8+6+10+8+6=60 given
there are 80 students so 80-60=20
c)only history so 6
d)no political science so both english and history so 12+10+6=28

Answer / smitha

Suppose g be the no. of students taking all three subjects.

therefore, g = 6

Suppose "e + g" students take english and history, "d + g"
students take english and political science, "f + g"
students take political science and history, thus,

e + g = 16
f + g = 16
d + g = 14

Let a, b, c be t he number of students taking only English,
History or Political science respectively.

Thus, we get the following equations:

a + e + g + d = 36
b + e + g + f = 32
c + d + g + f = 32

Solving the above 7 equations we get,

a = 12, b = 6, c = 8

Thus answers are as follows:

a) 12 (bcz a = 12)
b) 80 - (a+b+c+d+e+f+g) = 80 - 60 = 20
c) 6 (bcz b = 6)
d) 10 (bcz f = 10)
e) (a+b+c+d+e+f+g) - (c+d+f+g) = 60 - 32 = 28
