Question

 Có hai can dầu , can thứ nhất chứa nhiều hơn can thứ hai 10 lít và biết nếu chuyển từ can thứ hai sang can thứ nhất 10 lít thì lúc này số dầu trong can thứ hai bằng 2/3 số dầu trong can thứ nhất . Vậy lúc đầu trong can thứ nhất có bao nhiêu lít dầu ?
=> Ghi cách giải ra giùm

Answer 1

Sau khi chuyển từ can thứ hai 10 lít sang can thứ nhất thì can thứ nhất có số dầu nhiều hơn can thứ hai là:

\(10\times2+10=30\) (lít)

Hiệu số phần bằng nhau:

\(3-2=1\) (phần)

1 phần tương ứng với 30 lít  thì số dầu ở can thứ nhất lúc đầu là:

\(30\times3-10=80\) (lit)
