This can help reduce the chances of getting Alzheimer's disease.
This are some of the questions you can start solving and have fun :D

Steps:
1 + 1 =2
2 + (1 * 3) = 5
5 + (3 * 3) = 14
14 + (9 * 3) = 41
41 + (27 * 3) = 122
122 + (81 * 3) = 365

Ans - 365

2) My Mother was 27 when I was born. 8 years ago she was twice as old
as I shall be in 5 years' time. How old am I?

Steps:
You are "A" years old and Your mother is "A" + 27 years old.
8 years ago, your mother was "A" + 27 - 8 = "A" + 19
In 5 years time, You will be "A" + 5
"A" + 19 is twice as much as "A" + 5
So A + 19 = 2 ( "A" + 5 )
"A" + 19 = 2"A" + 10
"A" = 9
So you will be 9 years old and your mother will be 9 + 27 = 36

Backword checking:
8 years ago, you were 1 years old, your mother will be 28 years old
5 years later, you will be 9 + 5 = 14 years old

Ans - 14 years old

3) Lets say if

2 + 3 = 10
  6 + 5 = 66
   7 + 2 = 63
   8 + 4 = 96

   Then what is 9 + 7 equals to?

» Click to show the answer «

First Step:

logically 2 + 3 = 5 but in this case it equals to 10

and 4 + 4 = 8 but in this case it is 32 

and 6 + 5 should be 11 but 66.

By listing them out we found out that there is a pattern in this question.

In all the cases, all the number is being multipied by the first number thus

giving the answer of 10, 32, 66, 63 and 96 respectively

2 + 3 = 5  ( * 2 ) = 10

4 + 4 = 8  ( * 4 ) = 32 and so on and

thus 

9 + 7 = 16 ( * 9 ) = 144

Answer: 144
