Joe’s father will be twice his age 6 years from now. His mother was twice his age 2 years before. If Joe will be 24 two years from now, what is the difference between his father's and mother's age?
Read Solution (Total 12)
-
- (J + 6)*2 = F + 6 ---(1)
(J - 2)*2 = M - 2 ---(2)
J + 2 = 24 => J = 22
put J=22 in (1) we get, (22+6)*2 = F + 6 => F = 50
put J=22 in (2) we get, (22-2)*2 = M - 2 => M = 42
so, difference between his father's and mother's age = F - M =(50-42)= 8 years

- ans: 8 years
(F+6) = 2 (J+6)
(M-2)=2(J-2)
Father age = 50
Mother age = 42
Joe's age = 22 - 10 years agoHelpfull: Yes(2) No(0)
- 6+X = 2f
x-2=2m
prsnt age 24
26+6 = 32
64
24-2 =22
44
64-44 = 20 years

- Joe's age= 24-2 = 22
F+6 = 44 =>F=38
M-2 = 44 =>M=46
so,difference between father's and mother's age = M-F = 8 Years - 10 years agoHelpfull: Yes(1) No(3)
- (j+6)*2=f
j+2=24
j=22
putting the value of j in the equation
(j-2)*2=m
(22-2)*2=46
present age f 60-6=54
54-46=8 - 10 years agoHelpfull: Yes(1) No(2)
- diffrnce will be 8 years.
- 10 years agoHelpfull: Yes(1) No(0)
- 8 years
Joe's age=24-2
Mother's age=22*2-2=42
Father age =22*2+6=50
Differnce=8 - 10 years agoHelpfull: Yes(1) No(0)
- Joe will be 24 yrs old after 2 years. So his present age 22.
6 years from now he will be 22+6=28 yrs. his father will be 2 times this age. So father age 2*28=56.
2 years before Joe was 20. His mom was 40. This time his father age was 48 so dad-mom =8 years - 9 years agoHelpfull: Yes(1) No(0)
- 2(J+6)=(F+6)
2(J-2)=(M-2)
given J's age after 2 years as 24
so present J's age is 22
substitute J's age in above eq's
we get F=M=50
so, difference is 0

- 12 is the difference
- 10 years agoHelpfull: Yes(0) No(5)
- diff is 10 yr
- 10 years agoHelpfull: Yes(0) No(4)
- Joe's present age =22
Let His mother's age = x
X-2 = 2(22-2) =>x=42
Similarly-
Let his father's age = y
y+6=2(22+6)=>y=50
So diff of father's and mother's age =
50-42= 8 - 7 years agoHelpfull: Yes(0) No(0)
