Answers :
Direction (1-5) :
1) Answer: c)
586 × [9234 ÷ ((48/100)*950)] = 36 × (750/4) + x + 4500
586*(9234/456) = 6750 + x + 4500
11866.5 – 11250
X = 616.5
2) Answer: d)
(54/100)*650 + (x/100)*120 – (40/100)*8880 = 7293
351 + 6x/5 – 3552 = 7293
6x/5 = 7293 – 351 + 3552
6x/5 = 10494
X = 10494*(5/6) = 8745
3) Answer: b)
(3/7)*245*(135/15) + x = (528/3) + 217
945 – x = 176 + 217
X = 945 – 176 – 217
X = 552
4) Answer: c)
(51/400)*2400 + (47/200)*800 + 2025 = (1125/25) + 4x
306 + 188 + 2025 – 45 = 4x
2474 = 4x
X = 2474/4 = 618.5
5) Answer: a)
(12/75)* (48/1136)*(32/96) * 10650 = (x/100)*500
24 = 5x
X = 24/5 = 4.8
Direction (6-10) :
6) Answer: c)
The total employees who got salary less than 25000 from company P
= > (1800/6)*5*(34/100) = 510
The total employees who got salary less than 25000 from company R
= > 1200*(32/100) = 384
Required difference = 510 – 384 = 126
7) Answer: a)
The total number of employees who got salary 25000 to 50000 from company Q, R and T together
= > 1800*(57/100) + 1200*(44/100) + 800*(53/100)
= > 1026 + 528 + 424 = 1978
8) Answer: d)
The total number of employees who got their salary above 50000 from company P = 270
(18/100)*total employees in company P = 270
Total employees in company P = 270*(100/18) = 1500
The total number of employees who got their salary less than 25000 in company P, Q and S together
= > 1500*(34/100) + 1800*(28/100) + (2*1200)*(38/100)
= > 510 + 504 + 912 = 1926
Required average = 1926/3 = 642
9) Answer: c)
The total number of employees who got their salary 25000 to 50000 from company S = 1152
Total employees in company S = 1152*(100/48) = 2400
Total employees in company Q and R together
= > 1800 + 1200 = 3000
The total employees in company S and T together
= > 2400 + 800 = 3200
Required % = (3000/3200)*100 = 93.75 %
10) Answer: b)
The total number of employees who got salary less than 25000 from company T
= > 800*(25/100) = 200
The total number of employees who got salary above 25000 from company Q
= > 1800*(72/100) – 96 = 1296 – 96 = 1200
Required ratio = 200: 1200 = 1: 6
