Total number of votes = x

A.T.Q,

60x/100 - 40x/100 = 6639

60x - 40x / 100 = 6639

20x/100 = 6639

20x = 663900

x = 66390/2

x = 33195 votes

Case I:

Maths = 76

science = 71

English = 62

Max. marks = 80×3 = 240

Marks obtained = 76+71+62 = 209

Percentage = 209/240 × 100

= 209/24 × 10

= 8.708 × 10

= 87. 08%

Case II:

maths = 76

science = 71

English = 26

Max. marks = 240

marks obtained = 76+71+26 = 173

Percentage = 173/240 × 100

= 173 × 10 / 24

= 1730/24 or 72.08%

Difference = 87.08 - 72.08 = 15%

Total students = 1200

boys = 60/100 × 1200 = 720

girls = (100-60)/100 × 1200 = 40×12 = 480

(i)

Number of boys = 720

Boys who like to play badminton = 40%

= 40/100 × 720

= 4×72

= 288 boys

(ii)

Number of girls = 480

Girls who like to play badminton = 30%

= 30/100 × 480

= 3×48

= 144 girls

(iii)

Total students = 1200

students who play badminton = 288 + 144

= 432

Percentage = 432/1200 × 100 = 36%

Aint got enough time for all of them, Sorry.
