Age Problem
the difference of two ages is 35. 8 years ago one of the persons age is 6 times of other .then what is the sum of both ages
Read Solution (Total 18)
-
- 65 years
x -y =35 ---(i)
(x-8)= 6(y-8) or x-6y=-40 ---(ii)
On solving (i) & (ii), x=50, y=15
Sum of ages=x+y=50+15=65 - 8 years agoHelpfull: Yes(13) No(0)
- x-y=36
x-8=6(y-8)
slove we get 65 - 8 years agoHelpfull: Yes(3) No(3)
- let 1st person's present age be x.
let 2nd person's present age be y.
then,the difference of the two ages be,
x-y=35
8 years ago,
1st person would be=x-8
2nd person would be=y-8
then,
x-8=6(y-8)
solving the two equations we will get,
x=50 and y=15
sum of both ages,
x+y=65

- simply the equation would be (x+8) -(6x+8)=35 where x is the age before 8 years...when one's age was x and that of another's was 6x....now after 8 years their age will grow by 8 years respectively...and now the difference between their age is 35 ...so do the sum according the process given above...

- Ya 65 is the sum

- x-y=35 --> x=35+y
x-8 = 6(y-8)
35+y-8 = 6y-48
5y = 75
y=15
x = y+35
x=50
x+y=15+50 =65 Ans

- Let the ages be x and y
x-y=35
x-8=6(y-8)
on solving we get
sum=65 - 8 years agoHelpfull: Yes(0) No(0)
- ans is 65..

- 65
six years ago their ages is 6x,x
now
present ages 6x+8,x+8
given that 6x+8-x-8=35
so x=7
then sum=65 - 8 years agoHelpfull: Yes(0) No(0)
- x-y=35
x-8=6(y-8)
on solving both we get
x=50
y=15
hence x+y=65 - 8 years agoHelpfull: Yes(0) No(0)
- 65years .assume both the ages to be x and y and u will get two equations based on the conditions solving that will give u the ages

- x-y= 35
8 years ago, x=6y
diff will remain same so from these two equation, we get x= 42 and y=7
in present i.e after 8 year sum= (42+8)+(7+8)= 65 - 8 years agoHelpfull: Yes(0) No(0)
- x-y=35 then x=35+y
x+8=6y+8
35+y+8=6y+8
35=5y
y=7
so x=35+7=42
then x+y=42+7=49
ans=49 - 7 years agoHelpfull: Yes(0) No(0)
- x-y=36
x-8=6(y-8)
slove answer is 50+15=65 - 6 years agoHelpfull: Yes(0) No(0)
- one is 15
other is 50
sum is 65 - 6 years agoHelpfull: Yes(0) No(0)
- (x-8)= 6(y-8) or x-6y=-40 ---(ii)
