$A$ can complete half work in $7$ days. So, speed of work of $A = \frac{x}{2\times 7} = \frac{x}{14}$ where $x$ is the amount of work to be done. <br />
<br />
Similarly speed of work of $B = \frac{x}{42}$<br />
<br />
Given that $A$ is doing half the work and $B$ is doing $1/3$ the work. So, remaining work $= 1 - 1/2 - 1/3 = 1/6.$ $C$ can complete $20\%$ of this in $28/5$ days. So,<br />
<br />
speed of work of $C = \frac{0.2 \times 5x}{28 \times 6} = \frac{x}{168}$<br />
<br />
Now, when $A, B$ and $C$ work together, their combined speed will be$ = \frac{x}{14} + \frac{x}{42} + \frac{x}{168} = \dfrac{12x+4x+x}{168} = \dfrac{17x}{168} $<br />
<br />
So, amount of time required $=\dfrac{x}{\frac{17x}{168}} = \dfrac{168}{17}$Quantitative Aptitudehttps://aptitude.gateoverflow.in/4724/self-doubt?show=4791#a4791Thu, 11 Oct 2018 14:46:44 +0000Answered: Ratio and Proportion

A/q , x / 7 = (96-x)/9<br />

A is a stronger player than B so probability of wining A is higher then probability of wining B .<br />
<br />
let W=win L=lost<br />
<br />
Probability of wining A to you = 3/4 , W= 0.75 L=0.25<br />
<br />
Probability of wining B to you = 1/2=0.50 L=0.5<br />
<br />
Case 1: AAB <br />
<br />
probability for you to win series = WWL + LWW+WWW= 0.25*0.25*0.5+0.75*0.25*0.5+0.25*0.25*0.5=0.15625<br />
<br />
Case 2: ABA <br />
<br />
probability for you to win series = WWL + LWW+WWW= 0.25*0.5*0.75+0.75*0.5*0.25+0.25*0.5*0.25=0.21875<br />
<br />
Case 3: BAB<br />
<br />
probability for you to win series = WWL + LWW+WWW=0.5*0.25*0.5+0.5*0.25*0.5+0.5*0.25*0.5=0.1875<br />
<br />

<p>We can clearly see that, the maintenance stage has the lowest average cost per man-month .</p>
<p>In the $1-5$ month span,</p>
<p>average cost per man-month in $1-2$ month is $40,000$</p>
<p>average cost per man-month in $3-5$ month is $20,000$</p>
<p>So, average cost per man-month in $1-5$ month is = $\dfrac{(40,000+20,000)}{2} = 30,000$</p>
<p>In the $9-13$ month span,</p>
<p>avg. cost per man-month in $9-10$ month is $15,000$</p>
<p>avg. cost per man-month is $10-13$ month is $10,000$</p>
<p>So, avg. cost per man-month in $9-13$ month is $\dfrac{(15,000+10,000)}{2} = 12,500$</p>
<p>In the $11-15$ month span, average cost per man-month is $10,000$</p>
<p>So, the $11-15$ month span will be having lowest average cost per man-month under the new technique.</p>
<p><strong>Answer is option C)</strong></p>Quantitative Aptitudehttps://aptitude.gateoverflow.in/3830/cat1996-159?show=4741#a4741Mon, 02 Jul 2018 08:51:13 +0000Answered: CAT1996-156

If the coding stage was performed in the $5^{th}$ month, then the cost will be $10,000 $ per man-month which is $10,000 \times 4 = 40,000$ because the coding stage was supposed to perform by $4$ people.<br />
<br />
But,<br />
<br />
now the design stage is performed in the $5^{th}$ month & $5$ people are working on that stage and for performing or doing the design stage the cost is $20,000$ per man-month, & the total cost will be $20,000 \times 5 = 1,00,000$ in the $5^{th}$ month.<br />
<br />
In the $5^{th}$ month, the cost was supposed to be $40,000$<br />
<br />
& now the cost incurred = $1,00,000$<br />
<br />
Percentage change in the cost incurred in the $5^{th}$ month = $\dfrac{(1,00,000-40,000)}{40,000} \times 100\% \\ = \dfrac{60,000}{40,000} \times 100\% \\ = \dfrac{6}{4} \times 100\% \\ = \dfrac{3}{2} \times 100\% \\ = 150\%$Quantitative Aptitudehttps://aptitude.gateoverflow.in/3827/cat1996-156?show=4740#a4740Mon, 02 Jul 2018 06:41:52 +0000Answered: Verbal Reasoning / Verbal Analogy HELP
