Answer: B
Explanation:
Step 1 – Calculate the % change by Department between Quarters 3-4 HR: (1,346 – 1,305) / 1,305 = 3.14%. Note: some people find it quicker to calculate 1,346¸ 1,305 = 1.0314 Marketing: (4,309 – 3,652) / 4,309 = 17.99% Sales: (5,245 – 5,091) / 5,245 = 3.02% IT: (956 – 938) / 956 = 1.92% Finance: (4,463 – 4,545) / 4,463 = - 1.80% R&D: (1,821 – 1,755) / 1,821 = 3.76% Step 2 – Calculate the next quarter’s expenses for each department HR: 103.14% x 1,346 = 1,1388 Marketing: 4,309 x 117.99% = 5,084 Sales: 5,245 x 103.02% = 5,403.7 IT: 956 x 101.92% = 974 Finance: 4,463 x 98.2% = 4,383 R&D: 1,821 x 103.76% = 1,889 Step 3 - Calculate the next quarter’s total expenses 1,388 + 5,084 + 5,404 + 974 + 4,383 + 1,889 = £19,122 Thus the correct answer is (B), £19,100
