- raja age now=22
father 2(22+6)-6=50
mother=2(22-2)=40
50+40=90 is the ans - 11 years agoHelpfull: Yes(4) No(4)
- answer is 92 i.e(50 + 42)

- CONSIDER RAJA AGE =22(FROM NOW AFTER 3 YRS HE WILL BE 25 SO NOW 22); IN 6 YRS HIS FATHER AGE =2X+6;FATHER=2(22)+6=50;BEFORE 2 YRS MOTHERS AGE =2X-2;
MOTHER=2(22)-2=42; SO SUM OF HIS PARENTS AGE =50+42=90 - 11 years agoHelpfull: Yes(3) No(3)
- 92 is correct one

- ans=66
raj's age now suppose=y
father's age= f
mother's age=m
f+6=2(y+6)
m=2(y-2)
y+3=25
y=22
f=26
m=40
f+m=66 - 11 years agoHelpfull: Yes(1) No(7)
- r=25-3=22
r fther=2*(22+6)-6=50
r mthr=2*(22-2)+2=42
parent sum=50+42=92

- let raj's father be f , mother be m and raj be x
given: f+6 = 2(x+6)
m-2=2(x-6)
x+3=25
thus x=22
f=50 , m=42
so sum is 92 - 9 years agoHelpfull: Yes(1) No(0)
- father=50years
mother=42years
total=92years - 9 years agoHelpfull: Yes(1) No(0)
- As acording to third condition 25years old from now means present age of Raj is 22 years
let fathers age be x and mothers age be y
in 6 years =(x+6=2*28) ((bcoz in six years raj age will be 22+6=28)
2 years ago=(y-2=2*20)
so from calculation x=50 and y=42
x+y=92 years - 9 years agoHelpfull: Yes(1) No(0)
- F+6=2(R+6)
M-2=2(R-2)
R=22
F+M=92 - 9 years agoHelpfull: Yes(1) No(0)
- I guess its 53

- Its all about matter of picking 3 different numbers at a time. i.e 8C3= (8x7x6)/(3x2x1) =56

- mr. K.M please explain your answer
- 11 years agoHelpfull: Yes(0) No(0)
- Father's present age=F. Mother's present age= M. Raj's present age= R.
R+3=25->R=22.
F+6=2(R+6) ---> F=50
M-2=2(R-2) ---> M=42
F+M=92 - 9 years agoHelpfull: Yes(0) No(0)
- answer is 92
if raj is going to be 25 years old 3 years from now.
therefore, raj's present age=(25-3)=22
Thus,
his father's age=[{2x(22+6)}-6]=50
his mother's age=[(2x20)+2]=42
so, sum of his parent's age now=92 - 9 years agoHelpfull: Yes(0) No(0)
- CONSIDER RAJA AGE =22(FROM NOW AFTER 3 YRS HE WILL BE 25 SO NOW 22); IN 6 YRS HIS FATHER AGE =2X+6;FATHER=2(22)+6=50;BEFORE 2 YRS MOTHERS AGE =2X-2;
MOTHER=2(22)-2=42; SO SUM OF HIS PARENTS AGE =50+42=92 - 9 years agoHelpfull: Yes(0) No(0)
- sum of his parent's age is 92.

- 110
x+6=2(y+6)
m-2=2(y-2)
y=22
solve
50+38+22=110 - 8 years agoHelpfull: Yes(0) No(0)
