To find the average sales (in thousands) of all the branches in the year 2010, follow these steps:

Sales of each branch for 2010:

C1: 59 thousand

C2: 87 thousand

C3: 69 thousand

C4: 51 thousand

C5: 89 thousand

Total sales = 59 + 87 + 69 + 51 + 89 = 355 thousand

Average sales = Total sales / Number of branches

Average sales = 355 / 5 = 71 thousand

∴ The correct answer is option (1).
