3 dimes, 2 nickels, and 3 pennies
Using standard American coins (1, 5, 10, 25 cents), the fewest number of coins to make $0.13 would be four -- one dime and three pennies. This number would be different in countries that use different denomination coins, such as the 2-cent piece.
This is only possible if you allow adding coinsNumber of coins in row x Number of rows = total number of coins5 x 2 = 10 coins4 x 4 = 20 coinsYou would need 10 more coins
dimes : all coins = 6 : 12+6+18 = 6 : 36 = 1×6 : 6×6 = 1 : 6 Dimes are ⅙ of all coins.

In the minimum coin change problem using dynamic programming, the minimum number of coins required to make a given amount of change is calculated by finding the optimal combination of coins that add up to that amount. This involves breaking down the problem into subproblems and finding the minimum number of coins needed for each subproblem. The final answer is the minimum number of coins needed to make the given amount of change.

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
The details of the method depend on -- How many coins are there in the whole pile ? -- How many of those are counterfeit ? -- Are counterfeit coins heavier or lighter than genuine coins, or is that not known ?
It depends, many low quality counterfeit coins are simply made in lead and would be essentially worthless, but a few high-quality counterfeit coins are actually made out of silver and would be worth the silver value.
