Question

Kittens weigh about 100 grams when born and gain 7-15 grams per day. If a kitten weighed 100 grams at birth and gained 8 grams per day, in how many days will the kitten triple its weight?

Answer 1

25 days. If the kitten weights 100 grams, for it to triple it's original weight it must become 300 grams. A difference of 200 grams. 8 grams goes into 200 grams 25 times. Therefore the kitten takes 25 days to triple it's original weight.
