Miles and Missiles

You are called for the final interview at National Air Force Academy(NAFA). The officer, Sir John Baldwin asks you a single question, which is going to decide your fate.

"Two missiles were shot towards each other. They were 14,600 miles apart when they started. One was moving at 14000 miles per hour and the other at 16000 miles per hour."

"Now listen carefully" he added, "If they collide, that will be the end of the world. You can diffuse them only if you know, how far apart they are one minute before collision. Can you ?"

Sir John paused and added, "Take your time, Sonny."

"If only I had my pencil, paper or calculator." You were thinking.

So, did you passed the test ?

Elementary, my dear Watson !

Sherlock Holmes and Watson were on a motorboat going downstream.

They overcame a raft at waterloo junction, an hour later they turned back* and after sometimes, passed the raft again, which was now six miles from the waterloo station.

"You know, what the velocity of the stream is?" said Sherlock Holmes.

"That is quite impossible to find Holmes" Watson exclaimed.

"Elementary, my dear Watson !" and then he explained how easily he can calculate the velocity of the stream just by knowing the fact that velocity is equal to distance divided by time.


It may be elementary for Sherlock Holmes, but can you ?


* assume the motorboat is in constant speed and no time was spend on turning the boat

Ina Meena Dika

Mr. Tito collecting data for census came across a house with three sisters Ina, Meena, and Dika. There were no straight answers when he enquired about their ages. This is what he was told

Ina said "All of us are above 24 years of age, Dika is the youngest, and ofcourse I am the eldest."

"The difference between Dika's age and mine is three years and the sum of my age and Ina's age is two more that twice Dika's age" told mathematician Meena. I am eldest if and only if Dika is not the youngest, she added.

Dika was more "clear" than others , she said "Meena is elder to me" and "Either I am 24 years old or Ina 25 or Meena 26" She added one more piece of vital information "Meena is not 27 years old"

To add to the confusion, Mr. Tito was told by a neighbour that one of the sister always lies and the other two always speak the truth. Can you help him find the ages?
