Q12.One day, a person went to horse racing area, Instead of
counting the number of human and horses, he instead counted 74
heads and 196 legs. Yet he knew the number of humans and horses
there. How did he do it, and how many humans and horses are
there?

Q14.What place in this world can have their temperatures Fahrenheit

Q15.You have two block of clay in cube form and the edges are 10
cm. How many spheres with a radius of 5 cm can you make with that
amount of clay
Q16.A 'snooker' table (measuring 8 metres by 4m) with 4 'pockets'
(measuring 0.5m and placed at diagonal slants in all 4 corners)
contains 10 balls (each with a diameter of 0.25m) placed at the
following coords:
2m,1m...(white ball)
...and red balls...
1m,5m... 2m,5m... 3m,5m
1m,6m... 2m,6m... 3m,6m
1m,7m... 2m,7m... 3m,7m
The white ball is then shot at a particular angle from 0 to 360
degrees (0 being north, and going clockwise).
Just to make it clear, a ball is 'potted' if at least half of the
ball is in area of the 'pocket'
Assuming the balls travel indefinitely (i.e. no loss of energy via
friction, air resistance or collisions), answer the
following:
a: What exact angle/s should you choose to ensure that all the
balls are potted the quickest?
b: What is the minimum amount of contacts the balls can make with
each other before they are all knocked in?
c: Same as b, except that each ball - just before it is knocked in
- must not have hit the white ball on its previous contact (must be
a red instead of course).
d: What proportion of angles will leave the white ball the last on
the table to be potted
This question is for my Cousin
