Question:
There is grassy square plot. One horse is tied at the mid point of one side of
the field and another horse is tied at the adjescent side of the first one. The
rope is just long enough for the horses to reach the centre of the square. Find
the ratio of the area of the commonly grazed part to the area of the square
field.
a) (pi-2)/8
b) (pi-2)/6
  three other options were also there.

hi.......

this is a simple question......consider a square with s>0,s<=a,y>0,y<=a

the 2 semicirles will hv cetre at (a/2,0) and (0,a/2) with a/2 as radius

find their pt of intersection and use integration to calculate its area........it will be in terms of a^2

and the area of the square is a^2................the aswer comes out to be pi-2/8

there is no need to apply integration this problem can be solved by simple geometry. Draw a square and draw two semi circles taking a/2 as a radius along the adjacent sides. u will observe thatthe commonly grazed area can be found by area of semicircle - area of right angle triangle taking a/2 as a radius. hence the answer will be (pi-2)/8

Hey,

Here is my interpretation:

When you say log x (base 10) = k

you are effectively saying that 10^k is x. See the log graph for more clarification.

Anyhow, if you take the negative base - not every positive number can be expressed as its power.

Therefore, negative base is not allowed.

Hope that helps.

Ashish.

CAT weekend batch starting on 30th of January

Class timings: Saturday 6:30-8:30am, Sunday 6:30-9:30am

Duration: 32 weeks

Model CAT: Post the classroom schedule, each member should receive 20 paper-based mock CATs and 10 Computer-based mock CATs

Other information: As always, IIM graduates will take a majority of the classes at Ascent Education (around 75% of the overall course). I will be handling most parts of quants for CAT. Batch-size will be small (less than 15 per batch) and so each student will get personalized attention

Course fee: Rs. 18,900 for the entire course.

Hi Prashant,

�

Ascent does offer a correspondence course for CAT. You can sign up for the course online and pay by credit card or an Internet Banking account. Alternatively, you can download an application form, fill it, enclose a DD for the fees and send it to us. Course material will be shipped to any part of India for a fee of Rs.4300. The course material covers all areas tested in CAT and includes 20 full length tests and 10 Mock CATs. The course material will be sent to you when you register and Mock CATs in the second week of October.

If you reside outside India in the US, UK, Europe, Japan, Middle East Asia, or Far East Asia and plan to take CAT, you can register for 2IIM's CAT Correspondence Course and receive the study material by courier. The fees INCLUDING international courier charges is Rs.10,250 (Rupees Ten Thousand Two Hundred Fifty Only). The fees, however, does not include import duties, if any, at the destination country.

You can get more info from this link -- http://www.2iim.com/IIM_CAT_classes_correspondence_courses/CAT_correspondence_course.shtml

Rajesh

The answer goes like this:-

x1 men can complete a work in D days

1 man complete it in x1*D days

x2 men can complete in (x1*D)/x2 days

y1 women in D days

1 woman in y1*D days

y2 women in (y1*D)/y2 days

In 1 day x2 men do x2/(x1*D) part of work

in 1 day y2 women do y2/(y1*D) part of work

so in 1 day x2 men and y2 women do w=(x2/(x1*D)) + (y2/(y1*D)) part of work

so total days they will take to finish it = 1/w

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
5 men do a work in 3 days
1 men do the same work in 3*5=15 days
more men less time or less men more time

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/(y1*D)} �total work

y2 women - 1 day - {y2/y1*D)} �total work

so, x2 men and y2 women - 1 day - [�{x2/x1*D)} +�{y2/y1*D)} ]�

�� = [ { (x2*y1)+(x1*y2) }/(x1*y1*D) ] �total work

hence x2 men and y2 women will take�[ (x1*y1*D)/{ (x2*y1)+(x1*y2) }�] �days to do the job...�

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 eqn (x2 women+y2women) in terms of x1 and y1 and put the time and work formula M1D1H1/W1=M2D2H2/W2

Sample problem 4u
If 10 men 0r 18 boys can do a work in 15 days,then in how many days the double of the work is done by 25 men and 15 boys?

10men = 18 boys => Men=(9/5) boys
Therefore, 25men+15boys=25(9/5)boys+15boys=60 boys.

Now substitute in the Time and work formula,M1D1H1/W1=M2D2H2/W2

(18*15)/1=(60*x)/2 => x=9 days.

Therefore, the double of the work is done by 25 men and 15 boys in 9 days.

Note:
The above steps can be done in mental by practice.Members,pls mail if there are more easy shortcuts so that we all can know.

Regards,
Vijay,

The answer goes like this:-

x1 men can complete a work in D days

1 man complete it in x1*D days

x2 men can complete in (x1*D)/x2 days

y1 women in D days

1 woman in y1*D days

y2 women in (y1*D)/y2 days

In 1 day x2 men do x2/(x1*D) part of work

in 1 day y2 women do y2/(y1*D) part of work

so in 1 day x2 men and y2 women do w=(x2/(x1*D) ) + (y2/(y1*D)) part of work

so total days they will take to finish it = 1/w

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 :�

{(5x-0.2x)/5x}*100 = 96%...�

i.e. mistaken value is 96% less than actual expected value...�

or actual value is 2400% more than the mistaken value...�

{(5x-0.2x)/0.2x}*100 = 2400%...�

in simple words,actual value is 25 times the mistaken value...�

and mistaken value is (1/25) times the actual value...�

i hope that helps...�

take care...�

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 be (x/5-5x)*100/5x. Negative sign indicates the result is lesser than the expectred result.

It is 5 squared = 25 %

so for n it is n squared decrease in percentage from the actual expected result.

Let the number be 25.

Original resultant should be 25x5= 125

But it is divided by 5

So new no. would be 25/5 = 5

Error = 125-5= 120

% error = (120/125)*100= 96%

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 the no. be 100.
as the no. shud be multiplied by 5 so 500
but divide dby mistake so 20

therefore
((500-20)/20)*100
2400

hope am right if not please send the correct solution
