b is correct ans.<br />
<br />
process to solve; fisrst let the quadratic equation be ax^2 + bx + c<br />
<br />
and x=0 as it is given from here we found c=1.<br />
<br />
and by putting x=1 we find a+b=2<br />
<br />
now final task as clu is given in question that max at x=1 is three so we all know maxima happens at x= – b^2 /4a<br />
<br />
so putting it into initial equation we find relation b^2 = -8a so now using this into a+b=2 we found a quaratic like<br />
<br />
(b-4)^2=0 so b=4 and a=-2 by putting all these values in first we found -2x^2+4x+1.<br />
<br />
hence at x=10 value is -159.<br />
<br />
note: if u dont know quadratic equation maximum better use derivative concept of finding maxima and minima.Logical Reasoninghttps://aptitude.gateoverflow.in/938/cat2014-50?show=4853#a4853Sun, 14 Apr 2019 12:54:35 +0000Answered: CAT2004-04

https://aptitude.gateoverflow.in/845/calculate-reservation-charge?show=4843#a4843
Let x be the reservation charge and h be the cost of half ticket. <br />
<br />
From condition 2:<br />
<br />
cost of total full ticket = cost of full ticket + cost of reservation <br />
<br />
400 = cost of full ticket + x<br />
<br />
hence,<br />
<br />
cost of full ticket = 400 – x<br />
<br />
<br />
<br />
From condition 1:<br />
<br />
cost of half ticket = ¾ * cost of full ticket<br />
<br />
= ¾ *(400 - x)<br />
<br />
cost of total half ticket : ¾ *(400 - x) + x<br />
<br />
<br />
<br />
From condition 3:<br />
<br />
Cost of total full ticket + 2*cost of total half ticket = 1050<br />
<br />
400 + 2* (¾ *(400 - x) + x) = 1050<br />
<br />
2* (¾ *(400 - x) + x) = 650<br />
<br />
¾ *(400 - x) + x = 325<br />
<br />
1200 -3x + 4x = 1300<br />
<br />
x = 100Quantitative Aptitudehttps://aptitude.gateoverflow.in/845/calculate-reservation-charge?show=4843#a4843Sat, 23 Mar 2019 20:47:10 +0000Answered: GATE2019-2MARKS

<p><strong>Which company had the widest range of share prices over the 5 years?</strong></p>
<p>Pilemin Airlines Share price range 1.45 - 180 = 35p</p>
<p>RentaBanga 1.55 - 170 = 15p</p>
<p>Rupt Bank 0.45 - 1.65 = £1.25</p>
<p>Cash Casinos 0.40 - 1.20 = 80p</p>
<p>Stackem Supermarts 1.55 - 2.00 = 45p</p>
<p> </p>
<p><strong>Which year had the widest range of share prices?</strong></p>
<p>2002 Range 0.4 - 1.95 = 1.55</p>
<p>2003 0.55 - 2.00 = 1.45</p>
<p>2004 0.85 - 1.75 = 0.90</p>
<p>2005 0.75 - 1.85 = 1.10</p>
<p>2006 0.9 - 1.65 = 0.75</p>
<p> </p>
<p><strong>Between 2002 and 2006 what was the approximate total change in share</strong></p>
<p>prices for all companies?</p>
<p>Total share price 2002 = £5.80</p>
<p>Total share price 2006 = 7.20</p>
<p>Percentage increase in price = (Change in price/original price) x 100</p>
<p>= (1.40 / 5.80) x 100 = 24.1% = + 25% to nearest 5%</p>
<p> </p>
<p><strong>If the proportional change in share price for Pilemin Airlines had been the</strong></p>
<p><strong>same as that for Rupt Bank between 2002 and 2006 what would have been the</strong></p>
<p><strong>value of Pilemin Airlines shares in 2006?</strong></p>
<p>Share price for Rupt Bank 2002 = £0.45</p>
<p>Share price for Rupt Bank 2006 = £1.65</p>
<p>Change in share price for Rupt Bank 2002-06 = 1.20 / 0.45 = 266%</p>
<p>Price of Pilemin Airlines shares in 2002 = 1.45</p>
<p>Increase in price of Pilemin Airlines shares 2002 - 2006 = Price in 2002 x Change in</p>
<p>share price for Rupt Bank</p>
<p>1.45 x 2.66 = £3.86</p>
<p>Therefore price in 2006 = original price plus increase in price = £1.45 + £3.86 increase</p>
<p>= £5.31</p>Quantitative Aptitudehttps://aptitude.gateoverflow.in/249/which-company-had-the-widest-range-share-prices-over-the-years?show=4840#a4840Sat, 16 Mar 2019 10:18:01 +0000Answered: made easy cbt 1 2019

Answer -1192<br />
<br />
To convert an integer to base b, divide it by b. The remainder is the ones place. <br />
<br />
convert 1982 to base 12 ,first 1982 divide by 12 that gives quotient – 165 and remainder- 2 So the number ends in a 2<br />
<br />
again previous quotient divide by base 12 , 165 divide by 12 that gives quotient – 13 and remainder- 9 So the number ends in a 92<br />
<br />
again previous quotient divide by base 12 , 13 divide by 12 that gives quotient – 1 and remainder- 1 So the number ends in a 192<br />
<br />
Finally, 1 is less than 12 so its representation is just 1, <br />
<br />
so result is 1192Quantitative Aptitudehttps://aptitude.gateoverflow.in/1232/cat2000-108?show=4832#a4832Sun, 20 Jan 2019 06:19:11 +0000altitude

$A$ 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 />

So, first part will be 42 and the second part will be 54<br />

assume you have tied all the women with a rope in order to ensure that they always remain together. Now , we have 5 groups i.e. 4 men and one group of women consisting of 3 women which is tied together.<br />
<br />
We can arrange group of 5 people in 5! ways <br />
<br />
Now, in women group which are tied ,among them 3 different women are there which can be arranged in 3! ways <br />
<br />
Now, both of them have to be together = 5! * 3! = 720Quantitative Aptitudehttps://aptitude.gateoverflow.in/4746/permutation?show=4787#a4787Mon, 08 Oct 2018 18:01:43 +0000Answered: Which language is directly understood by the computer without translation program?

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 />
Case 4: BAA<br />
<br />
probability for you to win series = WWL + LWW+WWW=0.15625<br />
<br />
so ABA sequence will maximize our chances to win seriese Ans=2Quantitative Aptitudehttps://aptitude.gateoverflow.in/4764/interview-question?show=4774#a4774Tue, 28 Aug 2018 10:29:01 +0000Answered: CAT 2007-06

<p>1/m+4/n=1/12</p>
<p>(n+4m)/mn=1/12</p>
<p>mn=12(n+4m)=12n+48m ----1</p>
<p>RHS will be even and it is given that n is odd so m should be even(even=even*odd).</p>
<p>n={1,3,5,...,57,59}</p>
<p>m={2,4,6,...,58,60}</p>
<p> by equation 1 we can conclude .. to get positive value of m n>48</p>
<p>so for n=49 </p>
<p> 49m=12*49+48m</p>
<p> <strong> m=588 this is also even </strong></p>
<p>n=51</p>
<p><strong>51m-48m=12*51 => 3m=12*51 => m=204</strong></p>
<p>n=53</p>
<p>5m=12*53=>m=127.2 which is not even integer</p>
<p>n=55</p>
<p>7m=12*55=> m=92.28 which is not even integer</p>
<p>n=57 </p>
<p><strong>9m=12*57=> m=76 this is valid </strong></p>
