The sum of the present ages of the father and his son is 60 years. six years ago fathers age was five times the age of son. After six years son's age will be?
[A] 16
[C] 20
[B] 28
[D] 17
Read Solution (Total 6)
-
- present f+s=60----1
six years ago the (f-6)=5(s-6)
f-6=5s-30
f-5s=-24----2
by solving 1 and 2 we get s=14 and f=46
after six years the age of the son is 14+6=20
- 10 years agoHelpfull: Yes(18) No(1)
- son present age is x
f=60-x
6 years ago
5(x-6)=60-x-6
5x-30=54-x
6x=84
x=14
ofter 6 years son age is 14+6=20years - 10 years agoHelpfull: Yes(3) No(0)
- f+s=60
(f-6) = 5*(s-6)
Solving both the equations we get s = 14 years,
So after 6 years age will be 20 years. - 10 years agoHelpfull: Yes(2) No(0)
- ans is 20 option c

- Let the present ages of son and father be x and (60 -x) years respectively.
Then, (60 - x) - 6 = 5(x - 6)
54 - x = 5x - 30
6x = 84
x = 14.
Son's age after 6 years = (x+ 6) = 20 years.. - 8 years agoHelpfull: Yes(0) No(0)
- f-6=5(s-6)
f=5s-24;
f+s=60
after solving
S=14
After six years
S=20 - 6 years agoHelpfull: Yes(0) No(0)
