Take Log on each side So we have x= z log75/log3 y= z log 75/log5 we put these value in the eq: xy/(2x+y) Cancelling out N solving it will give z as ANS I...
as many of u said ...96%change is correct according to me....consider the no.to be 5 itselfso...if it is multiplied by 5 the result is 25....n if it is divided...
hey hi , i think this is the way :- X1 men do work in D days => 1 day work of X1 men is 1/D similarly 1 day work of Y1 women is 1/D the result implies that ...

ans is 96%..... u take any no. say 5....so after dividing it by 5 we get 1 though the ans shud hav been 25...so %age change is 24/25 *100 =96% and it vl be...
hey i think it wil go as follows: let the no be x therefore x/5 instead of 5x (5x- x/5)/x*100 = (25x-x)/x*100 = 2400 thereis another way of doing it too. let...
It is 5 squared = 25 % so for n it is n squared decrease in percentage from the actual expected result. ... From: the boss <keerthi_indya@...> Subject:...
If x is the number and is divided by 5 mistakenly instead of multiplied by 5 then Expected reult: 5x Actual result : x/5 Percentage change in result would...
let the number be x... expected result is 5x... mistaken result is x/5 or 0.2x... so the percentage by which mistaken value is less than actual value is : ...

Hi sangita, Since the amount of work done by the x1 men and y1 women are equal, Put x1 men=y1women (ie) equate the no of men = no of women and bring the given...
x1 men - D days - total work 1 man - 1 day - {1/(x1*D)} total work x2 men - 1 day - {x2/x1*D)} total work y1 women - D days - total work 1 woman - 1 day -...
1 men = 1 women in D days efficiency of men and women is same 1men + 1 women done the same work in D/2 days. such type of question is done through logically ...
The answer goes like this:- x1 men can complete a work in D days1 man complete it in x1*D daysx2 men can complete in (x1*D)/x2 days y1 women in D days1 woman...
hi friends ,i want u to help me in solving this question: if x1 men or y1 women do a job in D days ,then how many days will be taken by x2 men and y2 women to...
