You have 8 marbles. 7 marbles weigh 1 ounce each, & one
marble weighs 1.5 ounces. You are unable to determine which
is the heavier marble by looking at them. You have a
weighing scale that consists of 2 pans, but the scale is
only good for 2 total weighings. How can you determine which
marble is the heaviest one using the scale & in 2 weighings?

Answer Posted / shaili & krishna
You can also put half of 8 marbels in both weigh scale means
half 4 in one & remaining half in another & then check which
scale is more heavier then avoid lighter one then take
heavier side marbels then put 2 in one weigh scale &
remaining in another. then check which is heavier take that
heavier part check it by puting one marbel in one weigh
scale & remaining in another.....
So you can get which is heavier from that 8 marbels
Suppose as example,
8
4 > 4
2 > 2
1(This is heaviest) > 1
