It's 3:00 AM in the morning. You are sleeping. The doorbell rings. It's your family, they want to have breakfast. They have got strawberry jam bottle, bread packet, honey bottle, juice bottle and milk bottle with them. So, what do you open first?
Thanks for the query.
Considering I have already opened up my eyes (since I have seen my family at the door from the view hole) I open up the door first. Otherwise, I open my eyes first.
i will open the door lock first
I want to buy a $1.00 newspaper. I have just enough pennies $0.01, nickels $0.05, dimes $0.10, and quarters $0.25 to buy the newspaper in every possible exact-change combination of those coins.
How many coins do I have?
Assume that you have a block weighing 40 kg and have tools to divide it as you want. Now, your task is to cut that block into 4 pieces such that only using those 4 pieces and a two-way balancing pan, you can measure any weight from 1 kg to 40 kg ? (You should be able to measure any weight like 1 kg, 2 kg, 3 kg upto 40 kg ).
