Few Tips & Tricks that will be helpful:

Multiplying a 2-digit number by a 2-digit number (Example numbers: AB, CD)

  • Step 1: BD (write only the unit’s digit and carry the rest)
  • Step 2: AD + BC + carry over (cross multiply and add, write a single digit and carry the rest)
  • Step 3: AC + carry over (write the complete number)

Example: 29, 53

  • Step 1: 9×3=27 (Write 7 and 2 is carried over)
  • Step 2: 2×3+9×5+2 (carried over) =53 (Write 3 and 5 is carried over)
  • Step 3: 2×5+5 (carried over) = 15 (write 15)

Answer: 1537

Multiplying a 3-digit number by a 3-digit number (Example numbers: ABC, DEF)

  • Step 1: CF (Write only the unit’s digit and carry the rest)
  • Step 2: BF + CE + Carried Over (Write only the unit’s digit and carry the rest)
  • Step 3: AF + CD + BE + Carried Over (Write only the unit’s digit and carry the rest)
  • Step 4: AE + BD + Carried Over (Write only the unit’s digit and carry the rest)
  • Step 5: AD + Carried Over (Write the complete number)

Example: 123, 456

  • Step 1: 3×6=18 (Write 8 and 1 is carried over)
  • Step 2: 2×6+3×5+1 (carried over) =28 (Write 8 and 2 carried over)
  • Step 3: 1×6+3×4+2×5+2 (carried over) =30 (Write 0 and 3 is carried over)
  • Step 4: 1×5+2×4+3 (carried over) =16 (Write 6 and 1 is carried over)
  • Step 5: 1×4+1 (carried over) =5 (Write 5)

Answer: 56088

Square of numbers ending in 5 (Example numbers: 65 X 65)

  • Step 1: Multiply the first number with the next number (6×7 = 42) and this becomes the first part of the answer
  • Step 2: 25 (5×5) is the second part of the answer
  • Solution therefore is: 4225

IBPS Clerk 2017 Exam FAQs

Few Important Formulas:

Geometry Theorems

  1. Pythagoras Theorem: AC2 = AB2 + BC2
  2. Apollonius Theorem: If AD is the median, AB2 + AC2 = 2 (AD2 + BD2)
  3. Angle Bisector Theorem: If AD is the angle bisector for angle A, AB/BD = AC/CD

Area (2D Figures)

  1. Area of a Circle = πr2
  2. Diameter of a Circle = 2r
  3. Circumference of a Circle = 2πr
  4. Area of a Rectangle = lxb (l=length, b=breadth)
  5. Area of a Square = a2 (a=side)
