Answer

Let the required number be 'X'


Condition 1 :  


XX = 2X  => 2X2 = X => X = 12


 


Condition 2 :


X × X = X2=> X = 12


 


Therefore, 12 is the number which becomes double when it is divided by itself and becomes half when it is multiplied by itself.

Q:

What is the Probability of all cars not clashing each other ?

triangular1504515041.jpg image

A) 1/8 B) 0
C) 1/4 D) 1
 
Answer & Explanation Answer: C) 1/4

Explanation:

Non collision can happen only when all the cars move in same direction.

That is either all cars moving in clockwise direction or all cars moving in anti clockwise direction.
P(all cars not colliding)

= P(all cars moving in the same direction)

= P(all cars moving in clockwise direction)  +  P(all cars moving in anticlockwise direction)

= [p(A --> C) x p(C --> B) x p(B --> A)]  +  [p(A --> B) x p(B --> C) x p(C --> A)]

= [1/2 x 1/2 x 1/2] + [1/2 x 1/2 x 1/2]

= 1/8 + 1/8

= 1/4
