put this solution on YOUR website!"the sum of the digit's of a three digit number is 14" __ h+t+u=14 __ h=14-t-u
"If the hundred's and unit's are interchanged the resulting number is 594 more than original"
__ h+10t+100u=100h+10t+u+594
__ substituting __ 14-t-u+10t+100u=1400-100t-100u+10t+u+594 __ 198u=1980-99t __ 2u=20-t
"ten's and the unit's digit are interchanged, the now number is more than the original by 36"
__ 100h+t+10u=100h+10t+u+36 __ 9u=9t+36 __ u=t+4
substituting __ 2t+8=20-t __ 3t=12 __ t=4
substituting __ u=4+4 __ u=8
substituting __ h=14-4-8 __ h=2
248 is the number
