At 6'o clock ticks 6 times means 5 interval
and also given that time b/w first and last tick is 30 sec.
so
30/5=6
i.e time of each interval is 6 sec.

Similarly at 12'o clock, clock ticks 12 times i.e 11 interval
so
1 interval time=6
so 11 interval=11*6
Answer=66 sec

Speed and time taken by both the birds are same, so distance(d) will be definitely the same. Let the distance between A and grain be x. By Pythagoras theorem, d^2= 200^2 + x^2 and d^2= 150^2 + (250-x)^2. Solving these, we get x=90 Ft.

I thing its 2rev/sec.
smaller ball has the radius R.
bigger ball has the radius 8R.
if smaller ball travel distance=16R(as it makes 16 rev per sec),the bigger one has to make(8R+8R=16R).

therefore,the bigger one has to travel twice its own radius,so the answer is 2 rev/sec.

11 Horses = 11 * 600 paise
11 Cows = 11 * 300 paise
10 Goats = 10 * 10 paise
6600 + 3300 + 100 = 10000 paise = 100 Rs
