Seven students sit in a row. If Ahmed is fourth from the left and third from the right, how many students are there in total?
- A. six
- B. seven
- C. eight
- D. nine
Explanation
Adding the two positions and subtracting one for the double count gives 4 plus 3 minus 1, which is 6. The stated figure of seven is therefore inconsistent with the positions, which is exactly the kind of check a careful candidate should make. Trust the arithmetic over the introductory wording.
