How you can pick out the pile of counterfeit coins in one step procedure using an equal arm balance?
you are given three piles of 10 pesos coins. one pile is made up of counterfeit coins heavier than the genuine ones. explain how can pick out the pile of counterfeit coins in one step procedure using an equal arm balance
Steven has nine gold coins that are identical in appearance but one is counterfeit using a balance scale how can he find the counterfeit in just two weighings?
The idea is that the counterfeit coin is lighter than the others, but not different enough to find by hand.Divide the coins into 3 groups of 3. Reserve one group and put the other two groups onto the balance scale.If they are the same, the counterfeit is one of the reserved group. Otherwise, the lighter pan has the counterfeit.Put one coin on each side of the scale and keep one off. If they are the same, the one not weighed is the counterfeit. Otherwise it is the lighter one.

How do you use the equal arm balance?
Before you begin using an equal arm balance, you must make sure the riders are an equal distance apart, and make sure the balance is balanced. Then, place the object(s) on one side of the balance, and the object(s) that you want to compare them to. Whichever object is closer to the ground is heavier. If the objects are equally levelled, they have equal mass.
If there are ten stacks ten coins each and counterfeit coins weigh twice as much as real ones How can you find the stack with counterfeit coins using a scale just once?
if the question allows you to use a scale once, use it in one of 2 ways. 1. Put all stacks of coins on the scale and remove 1 stack at a time, when the weight reaches the the correct amount for the number of stacks are on the scale then then counterfeit has been removed. 2. take 1 coin from stack 1, 2 coins from stack 2, etc. when looking at the numbers if each coin weights, lets say, 1 ounce, and stack 3 is the problem, the scale will read 3 ounces too many. If you can't use a scale, then sorry, your out of luck.
