    please explain ques set(2) step 2 ,,mine coming different 567 and 432 instead of 378 and 648

    1. 7*9*6 = 378

      Numbers of step II have been obtained by using at least 1 digit of each number in step I.

      1. Sunita Bhagat

        I take too much timeto solve puzzle , pls suggest any
        approach to minimise time

        1. Puzzles always remain time consuming.
          But if u do with full concentration then that can reduce time.
          While solving puzzles go on wriying any extra details separately on paper. Then try to inter relate them

  11. Sneha Dubey

    1st in 3:43 min
    2nd in 5:12 min

  12. sneha

    explain the 1st sum….not able to get

    1. Which step u dint get ?

      1. sneha

        second step too 🙁

        1. You have to keep this in mind:::: Numbers of step II have been obtained by using at least 1 digit of each number in step I.

          so 1st Q – 2nd step me
          8*9 – 6 = 66
