the age of both lee and Sam is 50 years. in 5years time Sam will be 4 times the age of lee. find their ages
~~~~~~~~~~~~~~~~~~
Let solve it MENTALLY.
Consider Lee and Sam in 5 years.
Their total age will be 60 years, and Sam will be 4 times as old as Lee.
Hence (it is obvious for a person able to calculate quickly in your mind) at that time
Lee will be 12 years years old, while Sam will be 48 years old: 48 + 12 = 60 and 48/12 = 4.
It means that now Lee is 12-5 - 7 years old, while Sam is 48-5 = 43 years old. ANSWER
-------------
