What will be the maximum sum of $44, 42, 40, \dots$ ?

Quantitative Aptitude in GATE CS evaluates foundational mathematical reasoning, arithmetic, algebra, combinatorics, elementary probability, and geometry through concise word problems and functional/graphical models. The questions emphasize direct application of core algebraic identities, logarithmic laws, rates, proportions, set intersections, and calculus-based optimization rather than heavy computation. Items are evenly distributed between 1-mark conceptual or single-step problems and 2-mark multi-step arithmetic, geometric, or conditional reasoning setups.
