Option 4 : 4992

Courses	% passed out
A	76
B	82
C	80
D	90
E	75

Courses	% passed out	% Failed
A	76	24
B	82	18
C	80	20
D	90	10
E	75	25

⇒ the total number of students is 60000

⇒ 100% = 60000

⇒ 1% = 600

⇒ Number of students in A = 18%

⇒ 18 × 600 = 10800

⇒ Number of students in C = 20%

⇒ 20 × 600 = 12000

⇒ Number of students failed in course A & C = (24% of 10800 + 20% of 12000)

⇒ (24 × 108 + 20 × 120)

⇒ (2592 + 2400)

⇒ 4992

∴ The number of students of Courses A & C who did not pass is 4992
