FUNNY MATHS ..CAN MATHS BE FUNNY?

The Puzzle: When asked about his birthday, a man said: "The day before yesterday I was only 25 and next year I will turn 28." This is true only one day in a year - when was he born?

The answer: He was born on December 31st and spoke about it on January 1st.

Age Calculation Tricks: Step1: Multiply the first number of the age by 5. (If <10, ex 5, consider it as 05. If it is >100, ex: 102, then take 10 as the first digit, 2 as the second one.) Step2: Add 3 to the result. Step3: Double the answer. Step4: Add the second digit of the number with the result. Step5: Subtract 6 from it.
