There are five dustbins along a circular path at different places. Ramesh takes multiple rounds of the path every morning, always at the same speed. He noticed that it took him a different number of steps to walk between any two consecutive dustbins. Ramesh also noticed that starting from any of the dustbins, it took a minimum 800 steps to reach every second dustbin. On the other hand, starting from any of the dustbins, it took a maximum 1260 steps to reach every third dustbin. If Ramesh's one step is 0.77 metre, and the width of the path is negligible, which the following can be the radius of the circular path?

If a, b, and c are all positive integers, with 4a > b, then which of the following conditions is BOTH NECESSARY AND SUFFICIENT for the expression ∛[(3)^a (21)^(3a−b) (49)^(2b+c)] to be a positive integer?

Consider the quadratic function f(x) = ax² + bx + a having two irrational roots, with a and b being two positive integers, such that a, b ≤ 9. If all such permissible pairs (a, b) are equally likely, what is the probability that a + b is greater than 9?

In a computer game, each move requires pressing a button. When the button is pressed for the first time, as a move, the computer randomly chooses a cell from a 4 × 4 grid of sixteen cells and puts an "X" mark on that cell. When the button is pressed subsequently, the computer ran…
