One day, Snow White asked the seven dwarfs about their birthdays. Dopey answered that
they were all born on the same day.
Snow White was taken aback and said, "But you don't look like septuplets'.
So Doc said that they were born on the same day, but on seven consecutive years and the ages
of the youngest three added up to 42 years?
(hint : Septuplates are seen babies born together on the same day and date by the same mother)

How old is Youngest dwarf
Solution:
Let say Youngest dwarf = x years old
Seven dwarfs were born on the same day, but on seven consecutive years
Hence their ages
x , x + 1 ,x + 2 ,x + 3 , x + 4 , x + 5 , x + 6
Youngest three are x , x + 1 and x + 2
x + x + 1 +x + 2 = 42
=> 3x = 39
=> x = 13
Hence their ages are
13 , 14 , 15 , 16 , 17 , 18 , 19
Youngest dwarf is 13 year old
