If 13 lions can kill 13 deers in 13 minutes how long will it take 100 lions to kill 100 deers?  Choices:
A) 1 minutes  B) 13 minute  C) 100 minutes  D) 10000 minutes  E) 1000 minutes

Rationale: "we can try the logic of time and work , our work is to kill the deers so 13 ( lions ) * 13 ( min ) / 13 ( deers ) = 100 ( lions ) * x ( min ) / 100 ( deers ) hence answer is x = 13 answer : b"
Answer: B
