haha.. it worked. Here is the maths (spoilers, do not read b4 u have tried the qn!): let a be the no. of chocolates, given 1<a<10 If bday passed, Age = 2007 - year born 2007 - year born = Age 2007 - year born + 100a - 250 = Age + 100a - 250 1757 - year born + 100a = Age + 100a - 250 1757 - year born + 100a + 250 = Age + 100a 50(2a + 50) + 1757 - year born = Age + 100a Left hand side is what the qn ask you to do. Right hand side is your (age + 100a). Assuming that your age is 2 digits, and given 1<a<10, 100a will be 3 digits. Hence, the first digit will be 'a', while the last 2 digits will be your age. For those who bdays not passed Age = 2006 - year born 2006 - year born = Age 2006 - year born + 100a - 250 = Age + 100a - 250 1756 - year born + 100a = Age + 100a - 250 1756 - year born + 100a + 250 = Age + 100a 50(2a + 50) + 1756 - year born = Age + 100a Haha.. therefore this qn only works this year!
