    8 ( 1 + 11 + 111 + 1111 + 11111 ).
  2. Count number of digits in each number,
    i.e, 1=1(digit), 11=2(digit), 111=3(digit), 1111=4(digit), 11111=5(digit), and write down all digits together that is 12345.
  3. Multiply 8 x 12345 = 98760.

  1. Take 3 Common and Replace all 3 with 1.
    3 ( 1 + 11 + 111 + 11111 ).
  2. Count number of digits in each number,
    i.e, 1=1(digit), 11=2(digit), 111=3(digit), 11111=5(digit), and write down all digits together that is 1235.
  3. Here 3 with four digit is missing. Keep this in mind and add an imaginary 4 in between 3 and 5. So, the number became 12345.
  4. Multiply 3×12345 = 37035.
  5. As we add an imaginary 4, Now we need to subtract 3333 from the result.
    i.e, 37035 – 3333 = 33702
    The final result is 33702.

      At first memorized 1 to 30 square and 1 to 30 cube and table of odd number from 1 to 30, which help you fast calculation. Onward you have to perform multiplication addition and division shortcut trick for that follow www.math-shortcut-tricks.com

  1. Shakthi says:

    Can you please send me the shortcuts tips and tricks for clearing out the aptitude round …I am tired of it ..Please do help me ,My mail shakthijayabal@gmail.com

  2. Shabnam S Ram says:

    How shall we calculate the addition of the similar digits when they are not increasing consecutively.Foe example:
    6+66+66+6666
    According to the above trick,it should be 6×1224=7344.
    however the actual answer is 6804.
    Please revert.

    • Ashish Kumar says:

      it is 6×1134=6840
      Plz understand the logic clearly
      Here after taking common we add things like this
      1111
      11
      11
      1
      ————–
      1134

    sir/madam i find difficult in clearing aptitude paper pls help to solve easily and interestingly kindly guide me for my bank exams

  5. Krishna says:

    i need a mathematical steps for 12345 = 555
    (1+4)(3+2)(5) like that 95381 = 888 (9-1)(5+3)(8) like that if any number given then the answer is similar value

  6. Kashyap says:

    This shortcut is good but only if number series are into the ascending order for example

    if have a case of
    6+66+666+6666 = 6(1234) = 7404

    but what if we have
    6+666+66+6666+6 = 6(13241) = 79446 which is wrong correct answer is 7410

    Is there is any short cut for the same?

  7. Jatinder Kumar Ahooja says:

    As at the start of the page, you gave the question – add:
    88888

    8888
    888
    88
    8
    ——————I need not write the answer to this question. As five eights followed by 4, by 3, by 2, by 1 are seen above. Who doesn’t know the table of 8? As we see five eights on the right most row, we know that 8 x 5 = 40. Here after, we see 4 eights, and we know that 8 x 4 = 32, write 32 in a complete manner. Likewise, we see that only 3 eights are to be added, write down 24, likewise 2 eights = 16 and finally a single 8, write down that as well. You may be wondering why I told you to do so! You’d understand the method in no time. As, I’d written 40, followed by 32, likewise 24, 16 and 8, write these numbers in a particular way,i.e., 40
    32
    24
    16
    08
    ———————– All you’ve to do is to note down 0 of 40, add 4 + 2 of 40 and 32 respectively
    Same way add 3 of 32 to 4 of 24; add 2 of 24 to 6 of 16 and finally note down the single 8 left. Do the addition from right to left, so to get the final total of the above in hardly any time.
