We are given that the product of three integers X, Y, and Z is 192.
$ X \times Y \times Z = 192 $
We know that Z = 4. Substituting this value:
$ X \times Y \times 4 = 192 $
Divide both sides by 4 to find the product of X and Y:
$ X \times Y = \frac{192}{4} $
$ X \times Y = 48 $
We are also given that P is the average of X and Y:
$ P = \frac{X + Y}{2} $
To find the minimum possible value of P, we need to find the minimum possible value of the sum $(X + Y)$, given that $(X \times Y = 48)$.
Since the options provided are positive values, we consider positive integer pairs for X and Y whose product is 48. We look for the pair with the smallest sum.
List the pairs of positive integers (X, Y) whose product is 48 and calculate their sum:
The minimum sum $(X + Y)$ among these pairs is 14, which occurs when X=6 and Y=8 (or vice versa).
Now, use the minimum sum to calculate the minimum value of P:
$ P_{min} = \frac{min(X + Y)}{2} $
$ P_{min} = \frac{14}{2} $
$ P_{min} = 7 $
Therefore, the minimum possible value of P is 7.
Ankita has to climb 5 stairs starting at the ground, while respecting the following rules:
1. At any stage, Ankita can move either one or two stairs up.
2. At any stage, Ankita cannot move to a lower step.
Let $F(N)$ denote the number of possible ways in which Ankita can reach the $N^{th}$ stair. For example, $F(1) = 1$, $F(2) = 2$, $F(3) = 3$. The value of $F(5)$ is ________.
Consider a spherical globe rotating about an axis passing through its poles. There are three points P, Q, and R situated respectively on the equator, the north pole, and midway between the equator and the north pole in the northern hemisphere. Let P, Q, and R move with speeds $v_P$, $v_Q$, and $v_R$, respectively.
Which one of the following options is CORRECT?
