Directions (1-5) :

Total number of students placed in campus interview from colleges P and Q together in 2017 = 70 + 200 = 270

Total number of students placed in campus interview from colleges P and Q together in 2019= 270 * 7/5 = 378

Total number of female students placed in campus interview from colleges P and Q together in 2016 = 40% of 50 + 30% of 160

= 40/100 * 50 + 30/100 * 160

= 20 + 48 = 68

Required percentage = (180 – 100)/100 * 100 = 80%

Required average = (70 + 150 + 160 + 200 + 150)/5 = 146

Total number of students accepted the job offer from the colleges P and Q together in 2015 = 60% of (180 + 150)

= 60/100 * 330 = 198

?= 256 + 169 + 225 + 121 = 771

?= (40 + 3)(40 – 3) + (50 + 4)(50 – 4) – (60 + 2)(60 – 2)

= 402 – 32 + 502 – 42 – 602 + 22

= 1600 – 9 + 2500 – 16 – 3600 + 4

= 479

? + 75 = 36 + 42 = 78

=> ? = 78 – 43 = 35

81 + 25% of  ? = 122

=> 25% of ? = 122 – 81 = 41

=> ? = 41 * 100/25 = 164

144 * 36 – 100 *? =-2016

=> 100 x ? = 144*36 + 2016

= 5184 + 2016 = 7200

=> ? = 72
