Solution:

110 kms

72927+110 = 73037 , a palindrome

Solution:

14 horses and 8 men.<br><br>If, A --> men and B --> horses<br>
So, A + B = 22 and 2A + 4B = 72<br>2 (22 - B) + 4 B = 72<br>44 - 2 B + 4 B = 72<br>44 + 2 B = 72<br>2 B = 72 - 44 = 28<br>B = 14 (horses)<br><br>
So, there are in the stable 8 men and 14 horses.

Solution:

99+9/9 = 100

Solution:

15dollars

The cost is equal to 3dollars for each letter in the fruits name.

Solution:

4

5/2 = 3 and 10/3 = x
(10/3)/(5/2) = 20/15 = 4/3
So x/3 = 4/3
x=4

Solution:

Solution:

54

It takes 3 hours for the Simpson & Stewie to meet.
so the eagle flies for 3 hours at 18 Km/hr = 54 kms

Solution:

The number is: 12345679
12345679 * 9 = 111111111
12345679 * 18 = 222222222
12345679 * 27 = 333333333
And so on...

Solution:

Let the length of the bridge be x meters.
Running towards the train, Charles covers 0.5x-10 meters in the time that the train travels x-4 meters. Running away from the train, Charles covers 0.5x+2 meters in the time that the train travels 2x-8 meters.

Because their speeds are constant, the following holds:

(0.5x-10) / (x-4) = (0.5x+2) / (2x-8)
which can be rewritten to
0.5x2 - 24x + 88 = 0
Using the abc formula we find that x=44, so the railway-bridge has a length of 44 meters.

Solution:

The riddle, the 'facts' of which may or may not be true, results in the following equation:

x/6 + x/12 + x/7 + 5 + x/2 + 4 = x

where x is Abhishek's age at the time of his death.

Therefore, salmna lived exactly 84 years.
