Hi ,
Let
at present
________
father age = x years
son age = y years
2 years ago
_________
father age = ( x - 2 ) years
son age = ( y - 2 ) years
after 2 years
__________
father age = ( x + 2 ) years
son age = ( y + 2 ) years
according to the problem given ,
father age = 3 times of the son age
x - 2 = 3 ( y - 2 )
x - 2 = 3y - 6
x = 3y - 6 + 2
x = 3y - 4 -------( 1 )
father age = 5 times of son age
x + 2 = 5 ( y + 2 )
x + 2 = 5y + 10
x = 5y + 10 - 2
x = 5y + 8 ------( 2 )
equation ( 2 ) = equation ( 1 )
5y + 8 = 3y - 4
5y - 3y = - 4 - 8
2y = - 12
y = - 12 / 2
y = -6
we got negative value ,
there is some mistake in the given data.
