Duck Rabit Dog Weight - Math Riddle
64. Math Riddles
Given that the weight of a Rabbit and a Duck is 10 kilograms, the weight of a Dog and a Rabbit is 20 kilograms, and the weight of a Dog and a Duck is 24 kilograms, what is the total weight of a Dog, a Rabbit, and a Duck?
Explanation :
Let the duck be ‘Du’
The dog be ‘Do’
The rabbit be ‘R’.
From the above picture,
we can form equations as,
R + Du = 10kg.…equation (1)
R + Do = 20kg….equation (2)
Do + Du = 24kg…equation (3)
& R + Do + Du = ?
Rearranging the equations,
equation (1) = R + Du = 10kg
Du = 10kg – R
equation (2) = R + Do = 20kg
Do = 20kg – R
Putting the values of Do & Du in equation (3),
Do + Du = 24kg
20kg – R + 10kg – R = 24kg
30kg – 2R = 24kg
2R = 6
Rabbit, R = 3kg
Substituting the value of R, in equation (1) & equation (2)
We get,
equation (1), R + Du = 10kg
3 + Du = 10kg
Duck, Du = 7kg
Also, equation(2), R + Do = 20kg
3 + Do = 20kg
Dog, Do = 17kg.
Adding the values of,
Do + Du + R = 3 + 7 + 17
Dog + Duck + Rabbit = 27kg.

A 35 year old woman - Math Riddle
71. Math Riddles
A 35 year old woman has 3 children. If you multiply the 3 children's ages, you get 36. If you add up the children's ages it's 13. And her oldest child plays basketball for 3 years. How old are the kids?
They are 2, 2, and 9.
Explanation :
If you list out the trio of factors that multiply to 36, you get: 1 1 36 = 38 1 2 18 = 21 1 3 12 = 16 1 4 9 = 14 6 6 1 = 13 2 2 9 = 13 2 3 6 = 11 3 3 4 = 10 If the sum is 13, as you can see, there are 2 options. When she sa ys her 'oldest' you know it cannot be {6, 6, 1} since she would have two 'older' sons, not an 'oldest'.

An Athlete jumping - Math Riddle
74. Math Riddles
An Athlete is jumping. However, every time she jumps she gets a bit more tired, and every jump goes 1/2 as far as her prior jump. Now, for her very first jump, she goes 1/2 of a foot. On her second jump, she goes 1/4 of a foot, and so on and so forth. How many jumps does it take for her to travel 1 foot?
She will never get to the 1-foot mark because you keep adding smaller and smaller amounts!
Explanation :
We will find the maximum value of this process, when this is carried out infinite times.
This process goes like a Infinite GP, whose
First term,a = 1/2ft.
Common Ratio, r = 1/2ft.
Maximum value of this process is One Foot when the athlete jumps forever or Practically, she will never complete her 1 foot.
Hence, Athlete will never complete. her complete .
Here,
As shown in Number line, since we are taking half distance of the previous one.
Starting from 1/2 ft. ,and ending at 1 foot.
The value always tends towardd 1 but never reaches one.

Can you find the missing number?
2
Explanation :
The answer will be 2. Look at how many closed areas there are.
9999 has 4 closed areas (the top of the '9').
8888 has 8 closed areas (the top and bottom parts of 8 and there are no other digits).
1816 has 3 closed areas (top and bottom of 8 and bottom of 6, and it has 2 other digits (3 * 2 = 6)).
1212 has 0 closed areas, (0 * 4 = 0),
Therefore,
1919 has 2 closed areas. (the top of the '9').
