Can you solve the number puzzle ? if,38+13=21,49+35=21,55+14=21,93+23=21,21+37=?

Answer 2

Given:

  A series is given

        38+13=21

        49+35=21

        55+14=21

        93+23=21

        21+37=?

To Find:

     Find value of  21+37=?

Solution:

First observing series, we can say that following pattern is used

• First multiply the digits of first number within the number.
• After multiplication of both numbers, subtract the second number from the first number.
• After doing this we get same result of all series.

      $38 + 13 = (3\times8) - (1\times 3) = 24-3 = 21$

      $49 + 35 = (4\times9) - (3\times5) = 36-15 = 21$

      $55 + 14 = (5\times 5) - (1\times4) = 25-4 = 21$

     

In the same way,

      $37+ 21 = (3\times7) - (2\times 1) = 21 -2 = 19$
