Question

If 5,7=37
8,4=20
10,6=34
4,6=?

Answer 1

Given data :  

Sets are

5;7=37    8;4=20     10;6=34

To find :  

The missing number in 6;4 = ?  

Solution :

Logic applied behind :

Let A, B, C are the three numbers in the given set respectively.

Then, apply C = ( A² - B²) / | A - B |

5;7=37, Here C = 37 :

A = 5, B = 7

Then, ( 5² + 7² ) / | 5 - 7 |

      = (25 + 49) / |-2|

      = 74/2

      = 37         [=C]

8,4=20, Here C = 20 :

A = 8, B = 4

Then, ( 8² + 4² ) / | 8 - 4 |

      = (64 + 16) / |4|

      = 80/4

      = 20         [=C]

10,6=34, Here C = 34 :

A = 10, B = 6

Then, ( 10² + 6² ) / | 10 - 6 |

      = (100 + 36) / |4|

      = 136/4

      = 34         [=C]

6,4=?, Here C = ? :

A = 6, B = 4

So, C = ( 6² + 4² ) / | 6 - 4 |

       = (36 + 16) / |2|

       = 52/2

       = 26         [=C]

So, 4,6 = 26 is the answer.
