Asked By: ganta.jyostna
| Asked On: Dec 23rd, 2011

If there are 30 cans out of them one is poisoned if a person tastes very little he will die within 14 hours so if there are mice to test and 24 hours to test, how many mice are required to find the poisoned can?

Answered by: joseph on: Sep 15th, 2014

29

Answered by: a on: Aug 22nd, 2014

For 30 cans @ 1 mice per can it needs 30*14 hours to get the result. so total minimum with 30 mice is 420 hours required. since we have 24 hours time left to find out . minimum mice required would be 420 hours/24 hours would be 17.5 mice or 18 mice to do the job in 24 hours

Answered by: AussieMike on: Sep 10th, 2014

I agree with Vin Total Balls = T = 20 G = 7 R+B < 13 so that means G+R+B < T, so there must be a fourth color X to make T=R+G+B+X = 20 X+(R+B) = 13 max(R+B) = 12 If we make the assumption that there m...

Answered by: Vin on: Nov 12th, 2013

The Question is wrong

if R+B+G=20

and G = 7

so R+B+7=20

R+B=13

So R+B < 13 does not hold good

Product of irrational roots...

X= ((1/2)*(4+√10))*((1/2)*4-√10)

X=3/2

For this question we should realize the answer through answer only...we should substitute the options then finally we can recognize the correct answer...if we substitute 3/2 instead of x,we will get zero...by substituting other answers we can't...then the answer is 3/2
