The Answer :
1 = (5 / 5) x (5 / 5),
2 = (5 / 5) + (5 / 5),
3 = (5 + 5 + 5) / 5,
4 = ((5 x 5) – 5) / 5,
5 = ((5 – 5) / 5 ) + 5,
6 = ((5 x 5) + 5) / 5,
7 = 5 + ((5 + 5) / 5),
8 = (5 – (5 / 5)) / .5,
9 = 5 + 5 – (5 / 5),
10 = 5 + 5 x (5 / 5).

Answer
Using Pythagoras’ Theorem:
for the right-angled triangle in the figure
(r – a)2 + (r – b)2 = r2
Now, a = 6 cm and b = 12 cm. So,
(r – 6)2 + (r – 12)2 = r2 or
r2 – 2(6)r + 62 + r2 – 2(12)r + 122 = r2. This simplifies to
r2 – 36r + 180 = 0. On factorizing, we get
(r – 30)(r – 6) = 0.
Thus, the radius of the circle is 30 cm.
Area = 30 * 30 * pi.

Answer:
21 hours and 36 minutes. The exact size of the pipes and reservoir does not matter. If we label the large pipes L, the small pipes S and if the reservior has a total of T litres, then:
T / 6L = 12 which means L = T / 72
and
T / (3L + 9S) = 8 which means that S = T / 108
we want
T / 5S which gives 108 / 5 hours = 21.6 hours = 21 hours and 36 minutes.

The answer is:-
One person is chosen as the Counter. When a prisoner enters the living room, if the light is off they turn it on – but only if they have never switched it on before. When the Counter enters the room, if the light is on, they will turn it off. When the Counter has turned the light off 99 times, they will know that 99 prisoners have turned it on, and therefore every one of them has visited the living room and this will allow them all to be set free.
