Câu 6: Số tự nhiên lớn nhất có 5 chữ số mà khi chia số đó cho 2012 được thương và số dư bằng nhau là:
A. 98637 B. 99999 C. 98588 D. 96624
Cách giải
Gọi số tìm là A ( A là số tự nhiên có 5 chữ số )
Ta có:
A : 2012 = b dư b
=> A = 2012 . b + b
=> A = b . ( 2012 + 1 )
=> A = b . 2013
A lớn nhất có 5 chữ số nên b cũng phải lớn nhất với b . 2013 < 100000
Mà A < 100000 <=> b < 100000 : 2013 ~~ 49
Do đó b lớn nhất là 49 => b . 2013 = 98637
Vậy
Số cần tìm là 98637
