$$\text{Loss}=\text{Cost Price}-\text{Selling Price}$$ $$= 8000 - 7000 = 1000$$

Explanation

Profit = Selling price - Cost price = 600 - 400 = 200
Profit percentage = $\frac{\mathrm{<font\; color="\#0000ff">200</font>}}{\mathrm{<font\; color="\#0000ff">400</font>}}<font\; color="\#0000ff">\times </font>\mathrm{<font\; color="\#0000ff">100</font>}<font\; color="\#0000ff">=</font>\mathrm{<font\; color="\#0000ff"><span\; style="background-color:\; rgb(255,\; 255,\; 0);">50</span></font>}\mathrm{<font\; color="\#0000ff"><span\; style="background-color:\; rgb(255,\; 255,\; 0);">\%</span></font><span\; class="base"\; style="font-family:\; Overpass,\; sans-serif;\; font-size:\; 0.875rem;"><br></span>}$

Explanation

1 carton = 10 boxes × 12 cubes = 120 cubes
Total cartons needed = $\frac{\mathrm{<font\; color="\#ff0000">960</font>}}{\mathrm{<font\; color="\#ff0000">120</font>}}<font\; color="\#ff0000">=</font>\mathrm{<font\; color="\#ff0000">8</font><span\; style="font-family:\; Overpass,\; sans-serif;\; font-size:\; 0.875rem;"><br></span>}$

Explanation

Let income be $x$.
10% of $x$ = 1500
10/10​0×x=1500
$x=\frac{1500\times 100}{10}<br>$

​=15000
