Directions (6-7): Compare the value (only magnitude) of 2 quantities given in the question and give answer 

Q6. Quantity I: ‘x’: X, Y and Z can finish a work alone in 12, 18 and 9 days respectively. X started the work and Y and Z together assisted him on every 3rd day. ‘x’ is total days in which work is completed.

Quantity I > Quantity II
Quantity I < Quantity II
Quantity I ≥ Quantity II
Quantity I ≤ Quantity II
Quantity I = Quantity II or No relation
Solution:

Q7- There are 5 Red pens, 4 Black pens & 3Green pens in a bag. Four pens are chosen at random 
Quantity I: The probability of being 2 Red pens and 2 Black pens.
Quantity II: The probability of being 2 Red pens, 1 Green pen & 1 blacks pen.

Quantity I > Quantity II
Quantity I ≥ Quantity II
Quantity II > Quantity I
Quantity II ≥ Quantity I
Quantity I = Quantity II or Relation cannot be established
Solution:

Quantity I. (5C2 * 4C2)/12C4 = 60/495=4/33
Quantity II. (5C2 * 4C1 *3C1)/12C4 =120/495=8/33
Quantity II > Quantity I
