Product = 66,52,800? Edited by ginny007 - 16 years ago

k.. here's tha right answer..
Ginny.. urs is almost nearing.. i think we can spli 5 as 2&3 that makes a product of 6.
so, the answer goes like this.
Soln:
For maximum product we need to have maximum numbers and also we cannot have 1 since it is again tha same number.
Hence sum of 2+3+...+11=65
so 65-5=60.
And finally it is 2,3,4,6,7,8,9,10,11
Product = 7983360

A soldier looses his way in a thick jungle. At random he walks from his camp but mathematically in an interesting fashion.

First he walks one mile East then half mile to North. Then 1/4 mile to West, then 1/8 mile to South and so on making a loop.

Finally how far he is from his camp and in which direction?

Answer:
The soldier is 0.8944 miles away from his camp towards East-North.

It is obvious that he is in East-North direction.

Distance travelled in North and South directions
= 1/2 - 1/8 + 1/32 - 1/128 + 1/512 - 1/2048 + and so on... (a geometric series with r = (-1/4) )

   (1/2) * ( 1 - (-1/4)n )
= ---------------------------
        ( 1 - (-1/4) )

= 1 / ( 2 * ( 1 - (-1/4) ) )
= 2/5

Similarly in East and West directions
= 1 - 1/4 + 1/16 - 1/64 + 1/256 - and so on... (a geometric series with r = (-1/4) )

   (1) * ( 1 - (-1/4)n )
= ---------------------------
        ( 1 - (-1/4) )

= 1 / ( ( 1- (-1/4) )
= 4/5

So the soldier is 4/5 miles away towards East and 2/5 miles away towards North. So using right angled triangle, soldier is 0.8944 miles away from his camp.

There is a man who lives on the top floor of a very tall building. Everyday he gets the elevator down to the ground floor to leave the building to go to work.

Upon returning from work though, he can only travel half way up in the lift and has to walk the rest of the way unless it's raining! Why?

that is an easy one. the guy is incredibly short and lives on a floor whose button he cant reach. on rainy days he probably has an umbrella with which he is able to reach the button of the floor desired!!!

How much money did the restaurant lose? Ignore the profit of the food restaurant.
