tìm a,b,c

Answer 1

15abc0 : abc = 1010

(150000 + abc0 ) : abc = 1010

150000 : abc + abc0 : abc = 1010

150000 : abc + 10 = 1010

150000 : abc = 1010 - 10

150000 : abc = 1000

               abc  = 150000 : 1000

              abc = 150

Answer 2

15abc0:abc=1010

(150000+abc0):abc=1010

150000:abc+abc0:abc=1010

150000:abc+10=1010

150000:abc=1010-10

150000:abc=1000

abc=150000:1000

abc=150
