The original number will be 97
Explanation :
Let the digit at ten's place = x
and digit at one's place = y
so according to given conditions,
x = 2y - 5
=> x - 2y = -5....................eqn1
original number formed = 10x + y
Number formed by interchanging the digits = 10y + x
hence according to given conditions,
10x + y + 10y + x = 176
=> 11x + 11y = 176
=> x + y = 16
=> 2x + 2y = 32........eqn2
adding both the eqn we get,
3x = 27
=> x = 9
=> y = 16-x = 16 - 9 = 7
Hence the original number will be 10*9 + 7 = 97
