yes,I have proved it.
now digital=d,your age=y
(d*2+5)*50+y+365-615=100d+y
d is ur digital number,y is ur age.
But it can only be right when ur age is one-figure number or two.
Suppose someone is 100 years old,his last digital number is 2
100d+y=400,So it is not correct.^_^

Yes it sure is - and there are many more such math problems - I have done these before. Fun to do - thanks for sharing.

OMG, you are right! How do people figure out these types of mathmatical formulas? I admire anyone who has the ability to figure out these things. Did you come up with this formula?

Work it out ... if C is the cell's last digit and A your age you get
C, 2 times C, 2 times C plus 5, 10 times C plus 250, 100 times C plus 250 plus your age, 100 times C plus 615 plus your age, 100 tines C plus your age ... so of course it works ... unless you are over 100 years of age.
As with all this type of this ... work though the algebra (quite simple normally) and all becomes apparant.

Thanks for this tip and we need more like this discussion but our friends proved it on their responses:-
The formula leads to be equal (100X)+Y
where X is the last digit number & Y is your age.
