let the members be a1,b,c,d,e,f,g,h,i,j .Let a2 be the younger member who replaces a1.
we have,
a1+b+c+......+j=a2+b+4+c+4+d+4+.....+j+4
=> a1+b+c+....+j=a2+b+c+..+j+36
hence,the oldest member is 36 years older than the new memberibulal

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

In the given question. n(e^t)=n(e)+n(t)-n(e or t)
n(e and t)=n - neither who speak English nor Telugu=150-30=>120.
n(e and t)=n(e)+n(t)-n(e or t)
120=55+85-n(e or t)
n(e or t)=20.
n(only Telugu)=n(t)-n(e or t)=85-20 = 65.

There are a total of 150 weights. Let the number of 1 Kg weights be 'x'. Then the number of 2 Kg weights is '150 - x'. The sum of the weights is 260 Kg. ie [x * 1 + (150 - x) * 2] = 260. By solving this you will get 'x' as 40.

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?
Read Best Answer
Editorial / Best Answer
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

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...
