math : Honey Bottle

math : Honey Bottle

Post by Admin on Sun Aug 03, 2008 6:23 pm

Honey Bottle

A bottle fully contains honey. The honey bottle weighed 1.5kg. Then the bottle was weighed with half of the honey, it was 900 grams. Now guess what would be the weight of the bottle?

please show your calculation...

ok, i give the clue...

let's say h=honey, b=bottle
given... The honey bottle weighed 1.5kg
b + h = 1.5 -----------------------(equation 1)

the bottle was weighed with half of the honey, it was 900 grams.
so... b + 1/2 h = 0.9 -------------- (eq.2)

ok, anyone can continue it?

i am sorry bax.. your answer is wrong.. the calculation should be like this

the full weight(bottle+honey)=1.5kg
after half of the honey is gone(bottle+half of the total honey left)=0.9kg
meaning, 1.5kg-0.9kg= the weight of half of the total honey..
therefore the weight of half of the honey is 0.6kg.

back to the full weight, bottle + (2 x 0.6) = 1.5
bottle + 1.2kg = 1.5
bottle = 1.5-1.2
bottle = 0.3 kg..
