The dynamics of crowd behaviour are hard to study because usually people are not reliable witness of their own behaviour. Now consider 4 people standing in the queue of a supermarket. You want to predict their behaviour based on their age group. You get to know fro the supermarket records that their average age 3 years ago was 48 years. After a while, another person joins the queue and the present average of all the 5 is 46 years. The present age of the last person in the queue is:

Ans: 26 years There’s a farm having various birds of different weight. Farm has 23 birds weighing less than 15 gm, 35 birds weighing betweem 15 gm to 50 gm, and 12 birds weighing greater than 50 gm. One day accidentally a cunning Fox enetered the farm. After seeing so many birds see decided to pick some birds for its meal for next few days. Fox picked some birds from the farm and went away. How many total birds fox should pick so that it will have minimum 2 birds of each weight group.
