Step-by-step explanation:
Let the present ages of the man and his son be "x " and "y" respectively.
-------> (1)
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5 So,
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5 So,x−5=4(y−5)
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5 So,x−5=4(y−5)x−5=4y−20
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5 So,x−5=4(y−5)x−5=4y−20from equation (1)
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5 So,x−5=4(y−5)x−5=4y−20from equation (1) 3y−5=4y−20
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5 So,x−5=4(y−5)x−5=4y−20from equation (1) 3y−5=4y−204y−3y=−5+20
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5 So,x−5=4(y−5)x−5=4y−20from equation (1) 3y−5=4y−204y−3y=−5+20y=15
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5 So,x−5=4(y−5)x−5=4y−20from equation (1) 3y−5=4y−204y−3y=−5+20y=15x=3y
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5 So,x−5=4(y−5)x−5=4y−20from equation (1) 3y−5=4y−204y−3y=−5+20y=15x=3yx=3∗15=45
Let the present ages of the man and his son be "x " and "y" respectively.As per the question,x=3y -------> (1) Ages five years ago,age of father = x−5age of son =y−5 So,x−5=4(y−5)x−5=4y−20from equation (1) 3y−5=4y−204y−3y=−5+20y=15x=3yx=3∗15=45Hence, present ages of father and son are :-
