Đề bài:Cô Lan mua 2 quả táo và 3 quả cam với giá 84000 đồng. Cô hoa mua 4 quả táo và 5 quả cam với giá 150000 đồng. Tìm giá của 1 quả táo.
Bài giải:
Ta thấy:
2 quả táo + 3 quả cam = 84 000 đồng
4 quả táo + 5 quả cam = 150 000 đồng.
Ta thấy 4 chia hết cho 2.Do đó,ta có thể rút 2 quả táo => 0 quả táo và 4 quả táo => 2 quả táo.
Khi đó,ta có:
0 quả táo + 3 quả cam = 84 000 đồng
2 quả táo + 5 quả cam = 150 000 đồng.
Theo cách trên,ta có giá 1 quả cam là:
84 000 : 3 = 28 000 (đồng)
Gía của 5 quả cam là:
28 000 x 5 = 140 000(đồng)
Gía của 2 quả táo là:
150 000 - 140 000 = 10 000(đồng)
Giá của 1 quả táo là:
10 000 : 2 = 5000 (đồng)

A box of erasers cost 4 dollars. A box of pencils cost 6 dollars more. Darwin spent 240 dollars on some boxes of erasers and pencils. The ratio of the number of pencil boxes to the number of eraser boxes was 4:5. How many boxes of pencils did he buy?
Hint: Supppose that Darwin bought x eraser boxes, then he bought \(\frac{4}{5}x\) pencil boxs. (\(x\in N,x>0\)
Because Darwin spent 240 dollars so we have equation:
\(4x+\left(4+6\right).\frac{4}{5}x=240\)
\(\Rightarrow12x=240\Rightarrow x=20\)
So Darwin bought 20 eraser boxes and 16 pencil boxes.
Have a good time :))
