Thanks Answer by math_helper(2461) (Show Source):
The number N is written “htu” and has value 100h+10t+u
The digit reversal info leads to h=t+2
You are also directly given info that tells you
u = t+3
h+t+u = 11
By substituting, this leads to:
(t+2)+t+(t+3) =11
3t + 5 = 11
t = 2 ==> u = 5, h = 4
The number is 425
