Mathematics and Quantitative Aptitude

  • Percentage: part = (percent/100) × whole; percentage change = (new − old)/old × 100%.

  • Profit/Loss: Profit% = (SP − CP)/CP × 100; Loss% = (CP − SP)/CP × 100; SP = CP × (100 + profit%)/100.

  • Simple Interest: SI = P × R × T / 100; Amount = P + SI. Compound Interest: A = P(1 + R/100)^T; CI = A − P.

  • Average: sum of observations / number of observations; combined average = (n1×a1 + n2×a2)/(n1+n2).

  • Ratio and proportion: if a:b = c:d then ad = bc; continued proportion a:b = b:c → b² = ac.

  • Time and work: if A does work in x days and B in y days, together = xy/(x+y) days; work rate = 1/x per day.

  • Speed, distance, time: Speed = Distance/Time; relative speed (same direction) = difference, (opposite) = sum.

  • Area/Volume: circle area = πr², circumference = 2πr; rectangle area = l×b; triangle area = ½×b×h; cylinder volume = πr²h; sphere volume = (4/3)πr³.

  • LCM and HCF: LCM × HCF = product of two numbers; HCF of fractions = HCF(numerators)/LCM(denominators).
