AS, There are some readers such that in each occupied reading spot there are
different numbers of readers. 1+2+3+4+5+6+7+8= 36 readers so, 8 spots have
different readers. remaining are 23-8= 15. 15 spots are empty.

Hi,
I came up with another thought...
the numbers are 8,2,14,6,11,?,14,6,18,12
Now add the 1st number and the last number .. it is 20.
not add the 2nd number which is 2 and the last but one number which is 18 ... it is 20..
So if you keep adding these all the sum equals to 20. So the number next to 11 should be 9. Any thoughts :-)Sravani

Add the first and last number(i.e 8+12=20)
And add the second number and the number which second from last(i.e 2+18)
And so on............
Now the required answer is 9 (i.e 11+9=20) -

ans is 60 benches
let x=no of benches
y=no of students per bench
given
x*y=600,---------(1)
and given that 10 benches are less hence 2 students are seated more than per bench then
600=(x-10)*(y+2)
600=xy+2x-10y-20------------(2)
since xy=600
then eq(2) is
2x-10y=20
2x-10(600/x)=20
on solving
we get x=60prititripathi

10*60=60012*50=600it means per bench 10 student requirs 60 benches.but 10 are less so that on 50 benches to accomodate 12 per bench. it means 2 more to be seated on each bench. so the answer is 60.

To find the number of cats.
A number of cats got together and decided to kill between them 999919 mice. Every cat killed an equal number of mice. Each cat killed more mice than there were cats. How many cats do you think there were?

anirban_goswami- Member Since Feb-2008 | Mar 11th, 2008
No. of cats = x(say)
Therefore, no. of mice killed by each cat = 999919/x (since, they killed equal no. of mice)
Now, given that
(999919/x) is greater than x, i.e
999919/x > x, implies x*x<999919
Therefore, x < 999.95(approx). Now, the only no. which is nearest to but less than 999.95 and is a factor of 999919 is 991.
Thus, x = 991 and no. of mice = 999919/991 = 1009.amith.aec
- Oct 29th, 2010
Observing the num 999919 which is the total num of rats being eaten..we can write it as (1000000-81) = (1000^2-9^2) = (1000+9)(1000-9) = (1009)(991)so total num of rats killed =(1009)(9...
