Dịch: Trung bình cộng của 3 số là 32. Số thứ hai gấp 2 lần số thứ nhất, số thứ ba hơn số thứ hai 6 đơn vị. Tìm số thứ nhất?

Tổng 3 số bằng: 32 x 3 = 96

Coi số thứ nhất là 1 phần, số thứ hai là 2 phần như vậy, Số thứ ba là 2 phần và 6 đơn vị

Ta có sơ đồ sau:

6 số thứ nhất số thứ hai số thứ ba 96

Bớt số thứ hai đi 2 đơn vị

Tổng số phần bằng nhau là: 1 + 2+ 2 = 5 (phần)

5 phần ứng với 96 - 6 = 90 đơn vị

Số thứ nhất là: 90 : 5 x 1 = 18 

ĐS: 18
