Ivan had a bottle of honey. He used an equal amount of honey each day. At the end of the 12th day, 1/3 of the honey was left. At the end of the 14th day, the amount of honey left was 200ml.

Question

(a) What fraction of the honey was used each day?
(b) What was the amount of honey in the bottle? Give your answer in ml.

Answer 1

(a) 1/12 of the honey was used each day.
(b) The amount of honey in the bottle was 600ml.

Answer 2

original amount = 942.86 ml
used each day = 57.14 ml

proof: after 12 days =942.86 - 11*57.14 = 314.32
which is 314.32/942.86 or .333 or 1/3 of original

after 14 days, we have 942.86 - 13(57.14) = 200.04 ml
