The question should have been the dimensions of the brick are 4 times smaller than the original dimensions....then the explanation given that it weighs 1/16th is valid

A rich man wanted to distribute his collection of gold coins among his ten children comprising of 5 sons and 5 daughters. He also wanted to give some coins to his car driver. He proceeds on the following basis. The first coin went to the car driver and then 1/5th of the remaining coins to his first son. He then gave another coin to the car driver and distributed 1/5th of the remaining coins to his second son. This procedure went on till all the five sons received their share. Once all the sons received their shares, he distributed the remaining coins equally among his daughters. Can u find how many gold coins the rich man had? Ans i think is 881

Total Coins = 3121. 3121 = (3121-1), (3120 * 1/5), (2496-1), (2495 * 1/5), (1996-1), (1995 * 1/5), (1596-1), (1595 * 1/5), (1276-1), (1275 * 1/5), 1020Now divide in girls equaly = 1020 / 5 = 204 coins to each

2 artists are needed.
(2 artists in 2.5 hours can make 2.5 paintings.
In 22.5 (2.5*9) hours they will make 22.5 paintings.
In next one and a half hour they will make 1.5 paintings(this can be found by chain rule).
So in 24 hrs 2 artists will make 24 paintings) -

In a music concert, I was sitting only 100 feet away from the musicians.The performance was broadcasted. My sister who lives in Banglore also heard the same concert on the radio.

As far as iam concerned i think ur sister will hear the note before u.because via satellite the programme will be transmitted as electromagnetic radio waves which travels at a rate of 3*10^8 m/s.but the difference will be negligibly small that it can be picked up neither by u nor by ur sister.

Suppose The ships sail in straight lines and five of the six possible "collisions" are Known to happen. What else can you say about this situation? Specifically, will the Sixth collision occur, not occur, or does it depend on something else?
