If 6 cats can kill 6 rats in 6 minutes, how many cats will it take to kill 100 rats in 50 minutes? A look at four different solution methods for this sort of problem.
Read Solution (Total 4)
-
- 12 cats.
It is easy to note that no of cats is directly proportional to no of rats and inversely proportional to time
So, CT/R = constant (C for cats T for time and R for rats)
6 * 6 / 6 = x * 50 / 100
6 = x / 2
x = 12 - 13 years agoHelpfull: Yes(8) No(2)
- 200 cats...
- 11 years agoHelpfull: Yes(2) No(2)
- by d formula-
M1*W1 / T1 = M2*W2 /T2
M will be cat
W will be rat
T will be time
ans = 12 - 13 years agoHelpfull: Yes(0) No(4)
- 6 cats 6 rats 6 mints
1 cat 1 rat 1 minit
1 cat 50 rats 50 minits
2cats 100 rats 50 minits - 9 years agoHelpfull: Yes(0) No(1)
