A car manufacturer located 29 Km due west of chennai produces 250 carslour for export to Europe. However there is a problem in the paintshop and the lights have gone out. It seems that the cars can be painted only red and blue and nobody has noticed this except you as the cars come out of the testing area onto NH4: at random. What are the odds that 6 consecutive cars of the same colour will come through the test area at any one time(1 in ------------) ?

Answer the questions on the basis of the information given below. Coach John sat with the score cards of Indian players from the 3 games in a one-day cricket tournament where the same set of players played for India and all the major batsmen got out. John summarized the batting performance through three diagrams, one for each game. In each diagram, the three outer triangles communicate the number of runs scored by the three top scores from India, where K, R, S, V, and Y represent Kaif, Rahul, Saurav, Virender, and Yuvraj respectively. The middle triangle in each diagram denotes the percentage of the total score that was scored by the top three Indian scorers in that game. No two players score the same number of runs in the same game. John also calculated two batting indices for each player based on his scores in the tournaments; the R-index of a batsman is the difference between his highest and lowest scores in the 3 games while the M-index is the middle number, if his scores are arranged in a non-increasing order.
Q.How many players among those listed definitely scored less than Yuvraj in the tournament?
1) 0
2) 1
3) 2
4) More than 2
A set of positive numbers has the triangle property if it has at least one set of three distinct elements that are the lengths of the sides of a triangle whose area is positive. Consider set {4, 5, 6, … n} of consecutive positive integers such that all of it's ten-element subsets have the triangle property. What is the largest possible value of n?

A function f(x) is defined as f(x × y) = f(x) + f(y) for all positive real values of x and y. Find the value of f (1/128)
'D' is the absolute difference between a three-digit natural number and the sum of the digits of the number. If 'D' is a multiple of 12 and greater than 504, then how many values can 'D' assume?
A function f(x) is defined as (x + 1) × f(x + 1) + x × f(x) + (x – 1) × f(x – 1) = 0 for x ≥ 2 . If f(1) = 40
and f(6) = 180, find the value of f(14).
