Question 757533: i am 4 digit. my ones is twice my tens. my hundreds is five less than my ones. my thousands place is the sum of my tens and hundreds. what number am i? Answer by sachi(548) (Show Source):
You can put this solution on YOUR website! i am 4 digit. let abcd=1000a+100b+10c+d
my ones is twice my tens.
d=2c.............1
my hundreds is five less than my ones.
b=d-5=2c-5.......2
my thousands place is the sum of my tens and hundreds.
a=b+c=2c-5+c=3c-5...3
now the no is 1000(3c-5)+100(2c-5)+10c+2c=3212c-5500
this shows one more clue is missing as there are 4 unknowns & only 3 clues are present
put the other clue & try to solve or else mail me i will help out
thanx
