In the following series, a set of numbers is progressing with a particular patter. Can you deduce that pattern and find the missing set?
(2 + 6), (21 + 6), (58 + 6), (119 + 6), ___
210+6
The second digit in each set is 6.
If you add the numbers, you will find that they add up to be the cube of 2, 3, 4 and 5.
The next number is 6 and the cube of 6 is 216.
Thus, the last set will be (210 + 6).
In the given figure, can you find out the missing numbers?
The missing numbers are 8 and 7.
The middle number in the triangle is nothing but the square root of the sum of the numbers in the corner.
10 + 22 + 4 = 36
Square Root of 36 = 6
Similarly
10 + 42 + 12 = 64
Square Root of 64 = 8
12 + 22 + 15 = 49
Square Root of 49 = 7
This puzzle is for the Harry Potter fans. Do you know why Tom Riddle is called Lord Voldemort ?
If you have read The Chambers of Secrets, you should have known the reason. The phrase "I Am Lord Voldemort" can be used as an anagram to create "Tom Marvalo Riddle".
The book also explained that Voldemort wanted to distance himself from his father Rom Riddle who was a muggle. This was the reason for the change of name.
Lets play a word game. Following are some meaningless words that can be completed adding random letters on either sides of the word.
For an example, the word "rdo" can be formed into "pardon".
Using the same technique, can you complete the given words?
ecalc
airb
rinci
tibac
uidel
gorit
igna
eyho
The words can be re structured as:
Recalculate
Hairball (or airbag)

Can you find a rabbit in the given picture?
We have marked it for you. It is there in the left tusk of the elephant.
A car is crossing a 20km long bridge. The bridge can support at most 1500kg of weight over it. If somehow, the weight on the bridge becomes more than that, it will break.
Now, the weight of the car is exactly 1500kg. At the midway, a bird comes and sits on the roof of the car. This bird weighs exactly 200 gram.
Can you tell if the bridge breaks at this point or not?
The bridge will not break.
This is because when the bridge reaches the mid-point, it would have traveled 10km. While traveling 10km, the car would have used more than 200 grams of fuel. Thus, the weight of bird will not add much to the existing weight.
In a family, there are many children. Every boy in the family has as many brothers as the sisters. However, each girl has twice number of brothers as that of sisters.
Can you calculate the number of siblings in the given family ?
Suppose that the number of boys be "b" and number of girls be "g".
Now, each boy has equal number of brothers and sisters:
(b - 1) = g
=> (b - g) = 1 ------ (1)
In addition, each girl has twice as many brothers as sisters:
2 (g-1) = b
=> (2g - b) = 2 ------- (2)
From (1) and (2)
g = 3 and b = 4
Therefore, there are 4 boys and 3 girls in the family.
Can you find the number of triangles in the given figure?
The number of triangles in the given figure is 24.
DEAD, BALL, FEAR, SHOP
The above mentioned letters have been placed in that order using a logic.
Can you find that logic?
A = 1, B = 2, C = 3....
DEAD = 4 + 5 + 1 + 4 = 14
BALL = 2 + 1 + 12 + 12 = 27
FEAR = 6 + 5 + 1 + 18 = 30
SHOP = 19 + 8 + 15 + 16 = 58
Now, 14 < 27 < 30 < 58
Therefore, the order
DEAD, BALL, FEAR, SHOP
