Question and options
Uma ranked 8th from the top and 37th from the bottom in a class. How many students are there in the class?
- 47
- 46
- 45
- None of the given options is correct
Answer and explanation
Correct answer: D - None of the given options is correct
Uma has 7 students above her and 36 below her, so the class has 7 + 1 + 36 = 44 students, that is, 8 + 37 - 1. Since 44 is not among 45, 46 and 47, none of the numbers offered is correct; 45 comes from adding 8 and 37 without removing Uma, who is counted twice.
