The last digit of a 4-digit number is 2. If the digit 2 is moved to the start of the number, the new 4-digit number is more than 1098 the original number. Find the original number.
Hỏi đáp án là bao nhiêu? [ Tự dịch câu hỏi trên ].
Ta gọi số là abc2.
Ta có :
2abc - abc2 = 1098
2000 + abc - abc0 - 2 = 1098
Mà : abc0 = 10abc
(2000 - 2) - 10 x abc + 1 x abc = 1098
1998 - (10 - 1) x abc = 1098
9 x abc = 1998 - 1098
9 x abc = 900
abc = 100
Vậy số đó là 1002.
