Question

I am a three digit number. My ten digit is five more than my ones digit. my hundreds digit it s eight less than my tens digit. what number am I? Please explain

Answer 1

let units digit be x
x is greater than or equal to 0 and less than or equal to 9
tens digit is 5 more than units digit so
x+5<=9
x <=4
hundreds digit is eight less than x+5
x+5-8>=0
x-3>=0
x>=3
Therefore x>=3&x <=4
x={3,4}
Therefore number is either
083 or 194
But we know 083 is not a two digit number so correct answer is 194.
Hope this helps;:)
