Answers :

Direction (1-5) :

1) Answer: a)

(21/47) ÷ (180/235) × 140 + 3278 – 42 % of 900 = x

(21/47)*(235/180)*140 + 3278 – (42/100)*900 = x

X = 82 + 3278 – 378 = 2982

2) Answer: c)

(3/18) × 432 + (4/14) × 210 + (70/100)*500 = x – 1335

72 + 60 + 350 + 1335 = x

X = 1817

3) Answer: b)

90% of 12599 + 120% of 32999 – 635.92 = x

X = (90/100)*12600 + (120/100)*33000 – 636

X = 11340 + 39600 – 636

X = 50304

4) Answer: d)

(3/11)*187 × 25 ÷ 5 – x = (65/5) + 25

255 – 13 – 25 = x

X = 217

5) Answer: a)

12 (¾) – 5 (7/9) + 11 (1/5) – 8 (1/9) + 3 (½) = x

X = 13 – 6 + 11 – 8 + 4

X = 14

Direction (6-10) :

6) Answer: a)

Total number of students from college A

= > (78/100)*[(1400 + 1000 + 900 + 1800 + 2200 + 2600)/6]*(100/52)

= > (78/100)*(9900/6)*(100/52)

= > 2475

The total number of students participated in symposium events from college P, R and A together

= > 1400*(23/100) + 900*(32/100) + 2475*(48/100)

= > 322 + 288 + 1188

= > 1798

7) Answer: d)

Total number of students from college P and R together

= > 1400 + 900 = 2300

Total number of students from college Q and T together

= > 1000 + 2200 = 3200

Required % = (2300/3200)*100 = 71.875 %

8) Answer: b)

The total number of girls in college S and T together

= > 1800*(43/75) + 2200*(27/50)

= > 1032 + 1188 = 2220

The total number of boys in college S and T together

= > 1800*(32/75) + 2200*(23/50)

= > 768 + 1012 = 1780

Required difference = 2220 – 1780 = 440

9) Answer: c)

The total number of students in college B

= > [(1400 + 1000 + 900 + 1800 + 2200 + 2600)/6] – 380

= > (9900/6) – 380

= > 1270

10) Answer: a)

Total number of students from college P, R and U together

= > 1400 + 900 + 2600 = 4900

Total number of students from college Q, S and T together

= > 1000 + 1800 + 2200 = 5000

Required % = [(5000 – 4900)/5000]*100 = 2 % less
