Step 1 – Calculate the total 2011 sales (Online and for the High Street)
Online: £852,000 + £808,000 + £553,000 + £325,000 + £575,000 = £3,113,000
High Street: £644,000 + £483,000 + £336,000 + £456,000 + £678,000 = £2,597,000

Step 2 – Calculate the total 2012 sales (Online and for the High Street)
Online: £3,113,000 x 1.2 = £3,735,600
High Street: £2,597,000 x 88% = £2,285,360

Step 3 – Calculate the total 2012 sales (Catalogue)
£250,000 x 1.25 = £312,500

Step 4 – Sum the total January sales (Online, Catalogue and High Street)
£3,735,600 + £2,285,360 + £312,500 = £6,333,460 = £6,333,000 (to the nearest £1,000)

Thus the correct answer is (C), £6,333,000
