Age Calculation
Here you can find the age using some tricks. You can play these trick as instructed, with your parents or friends and prove your talent to them.
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.
Answer: That is your age.
Day of the Date
Here are some shortcuts/tips to find out the day of the week from the given date. You can play these trick as instructed, with your parents or friends and prove your talent to them.
Day of the Week:
January has 31 days. It means that every date in February will be 3 days later than the same date in January(28 is 4 weeks exactly). The below table is calculated in such a way. Remember this table which will help you to calculate. January 0
February 3
March 3
April 6
May 1
June 4
July 6
August 2
September 5
October 0
November 3
December 5
Step1: Ask for the Date. Ex: 23rd June 1986
Step2: Number of the month on the list, June is 4.
Step3: Take the date of the month, that is 23
Step4: Take the last 2 digits of the year, that is 86.
Step5: Find out the number of leap years. Divide the last 2 digits of the year by 4, 86 divide by 4 is 21.
Step6: Now add all the 4 numbers: 4 + 23 + 86 + 21 = 134.
Step7: Divide 134 by 7 = 19 remainder 1.
The reminder tells you the day. Sunday 0
Monday 1
Tuesday 2
Wednesday 3
Thursday 4
Friday 5
Saturday 6
Answer: Monday
One + one are two joke
Theorem: 1 + 1 = 2
Proof:
n(2n – 2) = n(2n – 2)
n(2n – 2) – n(2n – 2) = 0
(n – n)(2n – 2) = 0
2n(n – n) – 2(n – n) = 0
2n – 2 = 0
2n = 2
n + n = 2
or setting n = 1
1 + 1 = 2
Dollars equal ten cents joke
Theorem: 1$ = 10 cent
Proof:
We know that $1 = 100 cents
Divide both sides by 100
$ 1/100 = 100/100 cents
=> $ 1/100 = 1 cent
Take square root both side
=> squr($1/100) = squr (1 cent)
=> $ 1/10 = 1 cent
Multiply both side by 10
=> $1 = 10 cent
Three is equal to four
Three is equal to four
Theorem: 3=4
Proof:
Suppose:
a + b = c
This can also be written as:
4a – 3a + 4b – 3b = 4c – 3c
After reorganizing:
4a + 4b – 4c = 3a + 3b – 3c
Take the constants out of the brackets:
4 * (a+b-c) = 3 * (a+b-c)
Remove the same term left and right:
4 = 3
