no answer to it. haha.

skythewood SG

take note that you know what each coin should weight, and you know the set of 10 coins is off by hundredth of an ounce.

take 1 coin from set 1, 2 coin from set 2, and so on...

total of 55 coin.

if the weight of the 55 coin is off by 1 hundredth of an ounce from what it should weight if all is perfect, set 1 is the set with all coins faulty.

is 2 hundredth of an ounce off, set 2... 3 hundredth of an ounch off, set 3....

darkensun SG

Same answer as freedom,
1 coin from 1st bag, 2coins from 2nd bag, etc etc....
If 1st bag is with faulty coins, the weigh will be 10 oucne off, if 2nd bag is with fault coins, weight will be 20 ounce off, etc etc....

Two planes take off at the same exact moment. They are flying across the Atlantic. One leaves New York and is flying to Paris at 500 miles per hour. The other leaves Paris and is flying to New York at only 450 miles per hour ( because of a strong head wind ). Which one will be closer to Paris when they meet?

1983 singapore dollars is worth more than 1981 singapore dollars. why?

darkensun SG

cause 1983* $1= $1983 while 1981 only gives you $1981

Meia Gisborn SG

This is like a sudoku puzzle.

skythewood SG

imagine you are in a game show. the host show you 3 doors, 2 leading to a goat, 1 leading to a car. if you choose the car, you get to keep it. after you choose a door, the host will open one of the door with the goat, and you will than have the option to switch to the other door.

will you stay with the same door?

choose the other door?

or it doesn't matter?

Daisuke-kun SG

it does not matter there is no reward at all.

the game show is just a scheme of getting ur participating fees and tv ratings.

skythewood SG
