For each natural number k , Let C (k) denote a circle with radius k and centered at origin. A particle initially at (-1,0) moves k unit in the clockwise direction on C(k) and than moves radially to C(k+1).If the particle crosses the negative x axis for the first time on circle C(n). What is the value of n???
The whole numbers from 0 to 84 (both inclusive) are written, from left to right, on a thin, long metal sheet, in the ascending order, all along its length, such that the gap between any two consecutive digits is the same. If the sheet is now cut into four equal pieces along its length, using three cuts, what is the sum of the two digits on either side of the rightmost cut?

Hey puys.. do u always use the approximation method to find the sum of an infinite series?
m referring the method whr the ans depends only on the few initial terms..
It has ditched me at tyms..! dont kno how to identify whr to use..

2 boats A and B go upstream at a speed of 10 km/hr, where stream's speed is 5 km/hr. At noon, a snag develops in the engine of B and so it floats along the stream. A realizes the snag in B when the gap between them is 5 km. Then, A turns back and meets B. When would A meet B?

There is a deck of 52 playing cards. All the cards are placed face down in a straight line. First person comes and flips the position of all the cards, i.e. flips them face up. The second person comes and flips the position of all the cards which are placed at positions which are multiples of 2, i.e. if the card is face up, he will flip it face down, and if face down, he will flip is face up. The third person comes and flips the position of all the cards which are placed at positions which are multiples of 3, and so on. So, the nth person comes and flips the position of all cards which are placed at positions which are multiples of n. After all the 52 persons have flipped the positions of the cards, one after the other, which all cards will be face up?
