Banking Exam Math Shortcuts: Profit-Loss aur Percentage Tricks

Banking exams mein Quantitative Aptitude section mein time management bahut crucial hai. Ye shortcuts aur tricks aapko zyada questions sahi speed se solve karne mein help karenge.

💰 Profit-Loss Key Formulas

Formula Expression
Profit SP – CP
Loss CP – SP
Profit % (Profit/CP) × 100
Loss % (Loss/CP) × 100
SP (when profit%) CP × (100+P%)/100
CP (when SP and P% known) SP × 100/(100+P%)

⚡ Speed Tricks for Percentage

Trick 1: Percentage to Fraction Conversion (Yaad kar lo!)

Percentage Fraction Percentage Fraction
10% 1/10 12.5% 1/8
20% 1/5 16.67% 1/6
25% 1/4 33.33% 1/3
50% 1/2 66.67% 2/3
75% 3/4 37.5% 3/8

Trick 2: Successive Discounts/Profit Formula

Do successive changes (x% aur y%) ka net effect:

Net % = x + y + xy/100

Example: 20% profit ke baad 10% discount → Net = 20 + (-10) + 20×(-10)/100 = 10-2 = 8% profit

Trick 3: Marked Price Problems

  • If MP = x% above CP, aur discount = y%, then
  • Net profit% = x – y – xy/100
  • Agar x = y, tab bhi loss hoga (xy/100 ki wajah se)

Practice Questions with Solutions

Q1: A sells goods to B at 20% profit. B sells to C at 25% profit. If C pays ₹900, what did A pay?

Solution: C pays 900. B’s SP = 900. B bought at 900/1.25 = 720 (A’s SP). A bought at 720/1.20 = ₹600

Q2: A trader marks 40% above CP and gives 25% discount. Find profit%.

Solution: Net = 40 + (-25) + 40×(-25)/100 = 40-25-10 = 5% profit
