Read Solution (Total 7)
-
- let fathers age be 10x+y and sons age be 10y+x
so
10x+y-1=2(10y+x-1)
x=(19y-1)/8
put the values of x=1,2,3,4,5,,6,7
so at x=7 y=3
hence fathers age is 73 and sons age is 37 - 10 years agoHelpfull: Yes(14) No(0)
- 10x+y = xy
ex: 10 * 7 + 3 = 73 like this priya
in given pblm interchanging age of father means father age must be having in the form of 2 digit
i.e we are taking like that - 10 years agoHelpfull: Yes(4) No(1)
- do options verification
- 10 years agoHelpfull: Yes(3) No(1)
- praveen how 10x+y ??
- 10 years agoHelpfull: Yes(3) No(0)
- getting solution from the choice will be easy..provide options for it
- 10 years agoHelpfull: Yes(2) No(3)
- can u pls explain how it is solved
- 10 years agoHelpfull: Yes(2) No(3)
- My age : 10x+y
Son age : 10y+x
so 10x+y = 10y+x
10x+y-1 = 2(10y+x-1)
x = (19y-1)/8
for y=3
(19y-1) is completely divisible by 8
so x = 7
So my present age : 10*7+3 = 73
son's age : 10*3+7 = 37 - 4 years agoHelpfull: Yes(0) No(0)
