(((x*2)+5)*50)+1763-Year of Birth
On Simplifying you'll get 100x+250+1763-Year of Birth
i.e 100x+2013-Year of Birth
For example : the last two digits are "85" the result will be 8500+2013-year of birth, that will give the first two digits as the number you entered as its multiplied by 100 and your age till 2013.
