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.
