Given : The digit at ten’s place of a two digit number is greater than the square of digit at unit’s place  by 5

To Find :  the number formed

Solution:

Let say two  Digit number is

AB

1 ≤ A ≤ 9  ( As number is two digit hence A can not be zero)

0 ≤ B ≤ 9

The digit at ten’s place of a two digit number is greater than the square of digit at unit’s place by 5

A =  B² + 5

B = 0  => A = 5   Number = 50

B = 1   => A  = 6  Number = 61

B = 2  => A = 9   Number = 92

B = 3 => A = 14  > 9 Hence not possible

So possible numbers are

50

61

92
