To find out how many gram the puppy increase each day,here's what we can do:
weight of day 4 - weight of day 2
=365 - 305
=60g
To comfirm,we can use another pair
weight of day 4 - weight of day 2
=485-425
=60g
From the above,we can see that the puppy increase 60 grams each two days,meaning that it would increase 60÷2=30 gram each day.
We can then find its weight of age of 5 days:
365+30
=395g
Thus the answer is D.395
Hope it helps!
