3 Quarters (Quarter means 25 cents) 4 Dime (Dime means 10 cents) 4 cents

Total: $1.19

f I have less than $1 in coins, what is the largest amount of money I could have and not be able to give someone exactly 50p?

What is the least number of coins required to have an exact change for all possible items that cost from one cent up to and including one dollar in one-cent increments?

If I had 1.15 in my purse and totally 6 coins, but I could not give change for a rupee, half a rupee, quarter rupee, ten paise or five paise.

Which 6 coins did I have?
