Read Solution (Total 10)
-
- ANS: Sum of the age of raju's parents is(10 less than (4times of his age))=(4*r)-10
Let Raju's father age=F
Raju's mother age=M
Raju's age=R
f+6=2*(r-2) =>f+6=(2*r)-4
m=2*r
add both equations
(f+6)+(m)=((2*r)-4)+(2*r)
f+m+6=(4*r)-4
f+m=(4*r)-10 - 11 years agoHelpfull: Yes(10) No(6)
- Let Raju's father age=F
Raju's mother age=M
Raju's age=R
F+6=2(R+6)
F= 2R+6
M-2=2(R-2)
M= 2R-2
Therefore the sum of Raju’s Parent’s age is
F+M=2R+6+2R-2
F+M=4R+4
I.e., 4 more than four rimes Raju’s age - 11 years agoHelpfull: Yes(9) No(26)
- sol is 4R-2 where R is age of Raju
- 11 years agoHelpfull: Yes(2) No(4)
- let father's current age =F
mother's current age= M
raju's current age= R
F+6=2(R+4)
F=2R+2
M=2R
therefore
F+M= 2R+2R+2
F+M=4R - 11 years agoHelpfull: Yes(2) No(4)
- @ROHIT KUMAR : plz explain why F+6=2(R+6)?? its shud be F+6=2(R-2) ??
- 11 years agoHelpfull: Yes(2) No(2)
- let fathers age be y,raju's be x and mother's be z...
(y+6)=2(x+6)
2x-y=-6...(1)
z-2=2x-4
2x-z=2...(2)
therefore
z+y=8
ans=8.

- (4*r)-12, where r is the age of the raju
- 11 years agoHelpfull: Yes(0) No(0)
- ans: 4r
let age of raju is r
let age of fater be f
let age of mother be m
father's age after six years
(f+6)=2(r-2)
mother's age before two years(take it as two as its not specified)
m-2=2(r-2)
so 2(r-2)+2(r-2)=4r

- F+6=2(R-2)-eq1
M=2R
M+F=2R+2+2R
M+F=4R+2 - 11 years agoHelpfull: Yes(0) No(0)
- F+6=2(R+6)
F= 2R+6
M-2=2(R-2)
M= 2R-2
Therefore the sum of Raju’s Parent’s age is
F+M=2R+6+2R-2
F+M=4R+4
4 more than four times Raju’s age - 6 years agoHelpfull: Yes(0) No(0)
