ECE	13,750	9,625	4,125
Civil	11,000	6,000	5,000
EEE	5,500	4,400	1,100
CSE	8,250	3,630	4,620

Ans 1. Option C

(6,600+4,125+4,620+1,100)
16,445 (ans)

Ans 2. Option D

(Mech +CSE)/ (Civil + EEE)
(16,500 + 8,250) / (11,000+ 5,500)
24,750 / 16,500
3:2 (ans)

Ans 3. Option A

Male students studying in CSE dept. = (11/25)* 8,250
= 3,630
(3,630+4,125+1,100)
8,855 (ans)

Ans 4. Option C

2% (9,900) + 3%( 1,100)
198+33
231
231= X%(55,000)
X= (231* 100)/ 55,000
X= 0.42% (ans)

Ans 5. Option A

No. of female students in civil dept.= 5000
X% (55,000) = 5000
X= (5000 * 100)/ 55,000
X= 100/11
X= 9 (ans)
