Answer: A) Weight Explanation: An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example, the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system, if the system is divided in half, the mass and the volume change in the identical ratio and the density remains unchanged. Additionally, the boiling point of a substance is another example of an intensive property. For example, the boiling point for water is 100 °C at a pressure of one atmosphere, a fact which remains true regardless of quantity.

Answer: B) 32 Explanation: Let the total women in the group be 'W' Then according to the given data,  W x 20 = (W-12) x 32  => W = 32  Therefore, the total number of women in the group = 32
