i.e votes of P=0.4x-0.06x+0.15x=0.49x<br />

http://aptitude.gateoverflow.in/285/class-students-difference-between-highest-mark-least-mark?show=2964#a2964
let say t= total marks (addition of all the marks).<br />
<br />
here we have given 51 students (n=51)<br />
<br />
let say the average is x.<br />
<br />
so according to the standard formula of finding the average t/n=x<br />
<br />
t=51x.<br />
<br />
now, we can use any of the conditions <br />
<br />
according to case one:<br />
<br />
t-90/(51-1)=x-0.01x<br />
<br />
now take t=51x and solve it<br />
<br />
51x-90/(50)=0.99x<br />
<br />
x=60.<br />
<br />
here we get the same answer from the case 2 as well.<br />
<br />
Answer : x=60.Quantitative Aptitudehttp://aptitude.gateoverflow.in/285/class-students-difference-between-highest-mark-least-mark?show=2964#a2964Wed, 18 Jan 2017 03:04:13 +0000Answered: CAT2003-2-21

Lets examine each option :<br />
<br />
option a) F1(x) = –F(x) ; it will result the graph mirror image with respect to X -axis . So when we take the mirror image of F(x) with respect to X axis . we didnt get F1(x) . so option a is wrong <br />
<br />
option b) F1(x) = F(–x) ; it will copy the graph which is left to y axis to right to y axis and vice versa . As f(x) is symmetric to y axis . so you will not see any change in the graph of F(–x) . so this option is also not correct . <br />
<br />
option c) F1(x) = –F(–x) ; as we know from option b that F(-x) is same as F(x) . so -F(-x) will be same as option a . so this one is also not correct .<br />

<p>In this question no need to do any computation if and only if we carefully observe the prices of the 4 commodities.</p>

<p><strong>Arhar</strong>- The lowest pice of Arhar is greater than or Equal to that of Sugar.</p>
<p><strong>Pepper</strong>- The lowest price of Pepper is much much greater than Arhar.</p>
<p><strong>Gold</strong>(obviously costly :P )- The lowest price of Gold is Greater than that of Arhar.</p>
<p><strong>Sugar</strong>- The highest Price of Sugar is less equal to the lowest price of Arhar.</p>

http://aptitude.gateoverflow.in/248/what-was-the-percentage-increase-the-price-between-1998-2006?show=2917#a2917
<p><strong>(i) Percentage increase in the price of oil between 1998 and 2006.</strong></p>
<p>In 1998 it was 12.7 and in 2006 it was 65.1</p>
<p>so equation is 12.7*x = 65.1 which is x=5.1259% or 5.13%(round figure).</p>
<p>Hence, <strong>(5.) 5.13% is the answer.</strong></p>
<p><strong>(ii) If the total oil supply had grown at the same rate as the former USSR oil supply between 2000 and 2006 how much would this have exceeded the demand in 2006?</strong></p>
<p>rate of growth of former USSR oil supply between 2000 and 2006</p>
<p> In 2000 it was 7.9 and in 2006 it was 12.2</p>
<p>so the equation is 7.9*x = 12.2 which is 1.544%</p>
<p>According to question total oil suppy had grown @ the same rate i.e 1.544%</p>
<p>total oil supply in 2000 is 77.1 </p>
<p>so the after growth 77.1 * 1.544 = 119.0424</p>
<p>Now, According to the question : how much would this have exceeded the demand in 2006?</p>
<p>Total Demand in 2006 is 84.7</p>
<p>Difference is 119.0424 - 84.7 = 34.3424</p>
<p>Hence <strong>(5.) 34.3 is the answer.</strong></p>
<p><strong>(iii) In which year was the largest combined change in supply from the previous year for OPEC, the former USSR and other Non-OECD countries?</strong></p>

<p>total age after transfer from marketting to HR dept= 29*35=1015.</p>
<p>Initial total= 30*35=1050.</p>
<p>Decrease in total due to transfer from marketing to Finance dept=20. But total has to be maintained at 1015.</p>
<p>Therefore HR dept age total must have been increased by 35-20=15.</p>
<p>Hence new average of HR= 45*5+15=240.</p>

http://aptitude.gateoverflow.in/2908/nikita-28%25loss-kavya-94500-having-repair-profit-original-price?show=2910#a2910
Let the original price be $x$.<br />
<br />
Nikita's selling price = Nisha's buying price = 0.72x<br />
<br />
Nisha's selling price = Kavya's buying price = (0.72x + 3360) * 1.125 = 94500.<br />
<br />
So, $x = \left(\frac{94500}{1.125} - 3360\right)/0.72$<br />

Lets take sequence 1111...... 24 times , 11111.......... 26times (here each element of s1 is less than or equal to s2)<br />
<br />
reverse the sign of s1 then -1,-1,-1.,....... 24times . 11111.............26times<br />
<br />
Statement 1 is false . because every member of s1 is greater than or equal to s2. <br />
<br />
Statement 2 is false because max element 1 is not in s1. <br />
<br />
Statement 3 is false beacause in given above example both s1 and s2 are having same signs but after inverting the sign of s1 . largest of s1 and s2 are not in s1 . so it is also false . <br />
