EXPLANATION.
Let the age of shyam = x
Let the age of ram = 4x
Five years, ago.
Let the present age of shyam = ( x - 5 ) years.
Let the present age of ram = ( 4x - 5 ) years.
Ram was 7 times as old as shyam.
=> (4x - 5 ) = 7 ( x - 5 )
=> 4x - 5 = 7x - 35
=> - 5 + 35 = 3x
=> 30 = 3x
=> x = 10
Therefore,
present age of ram = 4x = 4(10) = 40 years.
present age of shyam = x = 10 years.
