<em>Solution</em><em>,</em>

<em>Let </em><em>the </em><em>ratios </em><em>be </em><em>5</em><em>x</em><em>,</em><em>4</em><em>x</em><em> </em><em>and </em><em>3</em><em>x</em>

<em>Now,</em>

<em>5</em><em>x</em><em>+</em><em>4</em><em>x</em><em>+</em><em>3</em><em>x</em><em>=</em><em>4</em><em>8</em><em>6</em><em>0</em>

<em>or,</em><em>1</em><em>2</em><em>x</em><em>=</em><em>4</em><em>8</em><em>6</em><em>0</em>
