Tổng 2 số là:

117 x 2 = 234

Vì khi viết thêm chữ số 1 vào bên trái số bé ta được số lớn nên số lớn hơn số bé 100

Số lớn là:

(234 + 100) : 2 = 167

Số bé là:

167 - 100 = 67

Tổng :

117 x 2 = 234

Viết thêm chữ số 1 vào bên trái số bé ta được số lớn => số lướn hơn số bé 100 đơn vị

=> Số lớn là :

( 234 + 100 ) : 2 = 167

Số bé là :

167 - 100 = 67

Tổng hai số là :

117 nhân 2 bằng 117

Nếu tổng là số có có 3 chữ số thì hiệu của hai số là một số có 3 chữ số, đặt số 1 vào bên trái số bé sẽ thành số lớn có nghĩa là số lớn hơn số bé 100 đơn vị .

Vậy :

Số lớn là :

( 234 cộng 100 ) : 2 bằng 167

Số bé là :

167 - 100 bằng 67

Đáp số : số lớn : 167 , số bé : 67

Tổng hai số là: 117 x 2 = 234
Nếu viết thêm chữ số 1 vào bên trái số bé thì được số lớn. Suy ra: Hiệu hai số là: 100
Số bé là: (234 - 100) : 2 = 67
Số lớn là: 234 - 67 = 167
