Do you really want to know your granny's age?
...this is a sneaky way to find out!!
Just follow these simple instructions:
- Ask the person to multiply the first number of his or her age by 5. (This is usually the tens digit, but if the person is less than 10 years old the first digit will be zero eg a five year old will be 05. If the person is over 100 then it will be both of the first two digits eg 103 will be 10)
- Then add 3.
- Then double the answer.
- Next ask the person to add the second number of his or her age to the answer.
- Ask them what number they have got. Subtract 6 from this answer and you will have their age!!
It is simple, Isn't it?
