</li></ol> <h2 id="content-id-9378256014-5"><b> Time And Work Questions Solution</b></h2><p>The correct answer is <strong>option 4</strong> i.e. <strong>10 days</strong></p>

<p>Given,</p>

<p>A + B = 10 days</p>

<p>B + C = 15 days</p>

<p>C + A = 20 days </p>

<p>and given conditions,</p>

<p>A + B + C = worked 6 days</p>

<p>B + C = worked 4 days</p>

<p>Total work = LCM of 10, 15 and 20 = 60 units</p>

<p>Efficiency of (A + B) = 60/10 = 6</p>

<p>Efficiency of (B + C) = 60/15 = 4</p>

<p>Efficiency of (A + C) = 60/20 = 3</p>

<p>A + B + C one day work = (6 + 4 + 3)/2 = 13/2</p>



<p> 
</p><p>Now,</p>


<p>A + B + C worked 6 days work = 6 × (13/2) = 39 units</p>

<p>B + C worked 4 days work = 4 × 4 = 16 units</p>

<p>Remaing work = 60 - (39 + 16) = 5 units</p>

<p>Efficiency of C = Efficiency of [(A + B + C) - (A + B)]</p>

<p>= (13/2) - 6 = 1/2</p>

<p>Time taken by C = Remaining work/Efficiency of C</p>

<p>= 5/(1/2) = 10 days.</p>

<p>Hence, remaining work done by C in 10 days.</p>
