It has been solved and explained by KD Live Experts under the guidance of Neetu Mam and they have tried to elaborate the concept used in Time   Work Questions.</p><h2 id="content-id-3095672841-3"><b>Question On Time   Work </b></h2>A can complete a project in x days, while B takes (x + 10) days for the same project. The ratio of their efficiencies is 3 : 2. If A and B work together for y days, they complete 50% of the total work. What is the value of (x + y)?

</li><li><p>26</p>
</li><li><p>28</p>
</li><li><p>30</p>
</li><li><p>32</p>
</li></ol> <h2 id="content-id-3072694158-5"><b> Time   Work Questions Solution</b></h2><p>The correct answer is <strong>option 2</strong> i.e. <strong>26</strong>.</p>

<p>The ratio of efficiencies of A and B is 3 : 2.</p>

<p>Since efficiency is inversely proportional to time taken, the ratio of time taken by A and B is 2 : 3.</p>

<p>Therefore, x : (x + 10) = 2 : 3</p>

<p>3x = 2x + 20</p>

<p>x = 20</p>

<p>Thus, A can complete the project in 20 days.</p>

<p>Efficiency of A = <span class="math-tex">\(1\over20\)</span>.</p>

<p>Let the efficiencies of A and B be 3k and 2k respectively.</p>

<p>Then, 3k = <span class="math-tex">\(1\over20\)</span></p>

<p>k = <span class="math-tex">\(1\over60\)</span></p>

<p>Therefore, their combined efficiency is = 3k + 2k = 5k = <span class="math-tex">\(5\over60\)</span> = <span class="math-tex">\(1\over12\)</span></p>

<p>Hence, A and B together can complete the entire project in 12 days.</p>

<p>They complete 50% of the work in y days.</p>

<p>Therefore, y × <span class="math-tex">\(1\over12\)</span> = <span class="math-tex">\(50\over100\)</span></p>

<p>y = 6</p>

<p>Thus, x + y = 20 + 6 = 26</p>
