Genel Yetenek — Sayısal Bölüm (Quantitative) for the KPSS Exam

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

• !Calculation errors in percentage and ratio problems under time pressure
• !Not setting up algebraic equations before solving word problems
• !Geometry errors: confusing area and perimeter formulas

Study tips

• 1Memorize the most common KPSS quantitative formulas: percentage change, ratio, area (triangle, circle, rectangle), volume.
• 2Practice word problems (sözel matematik) — convert the verbal description into an equation before solving.
• 3Time yourself on KPSS practice papers — aim for under 2.5 minutes per quantitative question.

1. 1

   Bir ürünün fiyatı %20 artırılmış, ardından %20 indirim yapılmıştır. Net değişim nedir? (A product's price was increased by 20%, then reduced by 20%. What is the net change?)

   • ADeğişim yok (No change)
   • B%4 azalma (4% decrease)Correct
   • C%4 artış (4% increase)
   • D%2 azalma (2% decrease)
   Why this answer?

   100 × 1.20 × 0.80 = 96. The net result is a 4% decrease. This is a classic KPSS trap — two 20% changes in opposite directions do NOT cancel out because the second 20% is applied to the already-increased price.
