General Mental Ability, Quantitative Aptitude and StatisticsNumber system and arithmetic
- ABoth the numbers are negative
- BExactly one of the numbers is negative
- CAt least one of the numbers is negative
- DNone of the above
Explanation
If a − b > a + b, cancelling a gives −b > b, i.e. b < 0: the subtracted number must be negative. The other number may be positive, negative, or zero (e.g. a = −5, b = −1 gives −4 > −6 with both negative), so “exactly one” and “both” are false in general. Hence (C), at least one of the numbers is negative.
