If age of a person is x and his mothers age is 34. then after how many years will the mothers age be twice of the son?
Read Solution (Total 7)
-
- let sons AGE=x, mother age=34.
from the given information we get
2(x+y)=34+y. solving this
2x+y=34.
so x= 15 and y=4 suitable. check it for after 4 years 15+4=19.
i. e 2(19)= 34+4= 38. after 4 years
mother is double of sons age. - 11 years agoHelpfull: Yes(14) No(5)

- 2(x+Y)=34+Y
Y=34-2x - 11 years agoHelpfull: Yes(9) No(0)
- Answer of this question based on option which u given..
- 12 years agoHelpfull: Yes(7) No(1)
- Ans will be according to the option..bt eqn will be 2(x+y)= (34+y)
y= no of years ask in question. - 11 years agoHelpfull: Yes(5) No(0)
- @ to option u can give solution
34=2*x+y
so more than 1 combination are possible
x=15,y=4 so 4 years
x=16 ,y=2 so 2 years - 10 years agoHelpfull: Yes(4) No(0)
- The eqn that can be formed from this question is
2x-34=y, where y being the no. of years that are needed.
So,give the options or data is incomplete. - 12 years agoHelpfull: Yes(1) No(4)
