My goal is to have $12. If I save $1 a month then it will take me 12 months to save $12. If I save $2 a month then it will take me 6 months to save $12. What if I saved $1.50 each month? How many months would it take me to save $12?
$ 12/ $ 1.5=8 months
Mice can multiply very fast. Adult mice can give birth once every month, and baby mice grow into adult mice in just two months after they are born.If you would buy a baby mouse just after it was born, how many mice would you have in 10 months?
I have many tongues, and must be fed. Restrain me not, and I will spread. I could save you, or make you dead, it all depends on how I'm fed. Who am I?
I want to fill my bucket using both cold and hot water. I have two taps for both cold and hot water. The hot water tap fills the bucket in exact 6 hours and the cold water tap fills the bucket in exact 4 hours. I turn both of them simultaneously but I forgot to turn off another tap which removes the water out of the bucket. This tap can empty the bucket in 12 hours.
How Long will it take to fill the bucket?
