Meeting a sales target

A salesperson must sell 600 units in a quarter. In the first two months she sold 170 and 190 units.

How many must she sell in the third month to exceed the target by 10%?

Show the answer and the worked solution

Correct answer: D.

300

Worked solution

  1. Target plus 10% = 600 × 1.10 = 660 units.
  2. Sold so far = 170 + 190 = 360.
  3. Required in the third month = 660 − 360 = 300.

Answer: 300.

The idea

Work out the adjusted target first, then subtract what has already been achieved.

Shortcut. She needs 240 more to reach 600, plus the extra 10% of 600 (60): 300.

Common trap. 240 — meeting the target exactly (600 − 360) and forgetting the extra 10% of 600.
