Nếu bớt số lớn 8 đơn vị thì số lớn chia cho số bằng 3. Khi đó ta có hiệu của số lớn và số bé là:
26 – 8 = 18
Số bé là:
18 : 2 = 9
Số lớn thực sự là:
9 x 3 + 8 = 35
Vậy hai số Hùng đố Dũng là 35 và 9.
câu 1 :
chữ số hàng đơn vị là :
15 : 5 = 3
chữ số hàng trăm là :
3 x 3 = 9
chữ số hàng chục là :
( 9 + 3 ) : 6 = 2
chữ sô hàng nghìn là :

Vậy số cần tìm là : 1923
