Easy Age Calculation

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. 

For Example, if your age is 43, 
               4 *    5 = 20
             20 +   3 = 23
             23 + 23 = 46
             46 +  3 = 49
             49  - 6  = 43
