if 15 lions can kill 15 deers in 15 minutes how long will it take 100 lions to kill 100 deers ?
we can try the logic of time and work , our work is to kill the deers so 15 ( lions ) * 15 ( min ) / 15 ( deers ) = 100 ( lions ) * x ( min ) / 100 ( deers ) hence answer is x = 15 answer : b
multiply(divide(15, 15), 15)
