Answers :
1) Answer: C
73 x 0.5 + 0.5 = 37
37 x 1 + 1 = 38
38 x 1.5 + 1.5 = 58.5
58.5 x 2 + 2 = 119
119 x 2.5 + 2.5 =Â 300
2) Answer: C
52 + 63Â + 6= 274
274 + 53Â + 5 = 404
404 + 43Â + 4 = 472
472 + 33Â + 3 = 502
502 + 23Â + 2 =Â 512
3) Answer: A
126 x 0.5 + 13Â = 64
64 x 1 + 23Â = 72
72 x 2 + 33Â = 171
171 x 4 + 43Â =Â 748
748 x 8 + 53Â = 6109
4) Answer: D
5) Answer: B
1290 x ½ = 645
645 x 2/3 = 430
430 x ¾ = 322.5
322.5 x 4/5 = 258
258 x 5/6 = 215
Directions (6-10):
Total number of employees = 400
Total number of IT employees = 150
Number of IT employees in company B = 25
Number of IT employees in company A = 2/5 * 125 = 50
Number of IT employees in company C = 3/5 * 125 = 75
Number of HR employees in company B = 50
Number of Sales employees in company B = 135 – 50 – 25 = 60
Number of Sales employees in company C = 25
Number of HR employees in A = 60 – 25 = 35
Number of HR employees in C = 75 – 35 = 40
Total number of HR employees = 50 + 35 + 40 = 125
Number of Sales employees in company A = 400 – 150 – 125 – 25 – 60 = 40
Total number of Sales employees = 40 + 60 + 25 = 125
Total number of employees in company A = 50 + 35 + 40 = 125
Total number of employees in company B = 135
Total number of employees in company C = 75 + 25 + 40 = 140
