25)A bacteria doubles itself each single day. It totally takes 15 days for the bacteria to fill a test tube. Find an approximate number of days for the bacteria to fill 1/3 of the jar.
Answer:
Though the question looks like a tough one, it is actually a simple question. If it takes 15 days for the bacteria to fill the entire test tube, on 14th day it would had filled half of the tube, on 13th day it would had filled a quarter of the tube and so on. Now 1/3th comes somewhere in middle between quarter and half filling of the tube. Hence the bacteria would need somewhere between 13 to 14 days to fill 1/3th of the jar.

Answer:
Again this is a very simple question which appears difficult. The entire course of Ram takes the form of a right angled triangle. Hence the time taken for him to travel back to A would be sqrt(3^2 + 4^2) = sqrt(25) = 5 hours.
