Pia and Ria start running simultaneously from the same point on a circular track of length 4200 m. If they run in opposite directions, they meet for the first time exactly after 2 minutes from the start and they meet at seven distinct points on the track. If they run in the same direction, they meet at three distinct points on the track. How much time (in minutes) does Ria take to complete one round, if she is the slower runner?

The micro manometer in a certain factory can measure the pressure inside the gas chamber from 1 unit to 999999 units. lately this instrument is not working properly.The problem with the instrument is that it always skips the digit 5 and moves directly from 4 to 6 . What is the actual pressure inside the gas chamber if the manometer displays 003016?

Two points are chosen uniformly at random on the unit circle and joined to make a chord C1. This process is repeated 17 more times to get chords C2,C3,…,C18. What is the expected number of pairs of chords that intersect?
Details and assumptions
If k chords intersect at the same point, this counts as (k 2) pairs of intersecting chords
Four players are playing a game involving choosing squares on a grid of size 3×8. Each player chooses a random square on the grid, then all players reveal their choices and a token is placed in the center of each of these squares. The probability that the tokens form the vertices of a non-degenerate rectangle can be expressed as ab where a and bare coprime positive integers. What is the value of a+b?
Details and assumptions
Players are allowed to have selected the same squares. There is no restriction on their choices. A degenerate rectangle has 0 area. Squares are rectangles.
A ship is moving at a speed of 30km/hr. To know the depth of the ocean beneath it, it sends a radiowave which travel at a speed of 200m/s. The ship recieves the signal after it has moved 500m. The depth of the ocean is?

Every morning ,at a certain time,Deepan opens a tap P into a tank T,and the tank gets filled exactly by noon,the very same day.One day some time after opening the tap she noticed a leak (that had developed earlier),after which she immediately plugged the leak and opened another tap Q simultaneously and managed to fill the tank by noon. Had she not spotted the leak the tank would have only been 50% full by noon and completely full by 3 PM.If the flow rate of Q is equal to that of P.
Find the time at which deepan opened Q.
