15 * 8 = 120

120 * 7 = 840

840 * 6 = 5040

5040 * 5 = 25200

25200 * 4 = 100800

125 + 23 = 148

148 + 26 = 174

174 + 29 = 203

203 + 32 = 235

235 + 35 = 270

21 + 42 + 18 = 55

55 + 52 + 20 = 100

100 + 62 + 22 = 158

158 + 72 + 24 = 231

231 + 82 + 26 = 321

24 + 72 =73

73 + 62 =109

109 + 52 =134

134 + 42 =150

150 + 32 =159

12 * 1.5 = 18

18 * 2.5 = 45

45 * 1.5 = 67.5

67.5 * 2.5 = 168.75

168.75 * 1.5 = 253.125

HR = 300 + 250 + 400 + 200 + 150 = 1300

Sales = 150 + 200 + 250 + 150 + 300 = 1050

Difference = 1300 – 1050 = 250

Total number of employees in IT department of D = 250

Total number of employees in IT department of A = 200/250 * 100 = 80%

Total number of employees in IT department of B = 150/250 * 100 = 60%

Total number of employees in IT department of C = 300/250 * 100 = 120%

Total number of employees in IT department of E = 350/250 * 100 = 140%

Company E has 40% more employees than company D.

Required percentage = [150/(300 + 400 + 250)] * 100 = 16%

Required ratio = (250 + 200 + 150):(200 + 300 + 150)

= 600:650

= 12:13
