X is 6 years younger to Y.After 5 years the ratio of ages of X and Y is 1:2. Now X's
father is 20 years older to Y and Y' father is 30 years more than X. What is the age of X and Y together?
(a) 12 (b) 8 (c) 18 (d) 6

• Fathers ages are irrelevant. From the question we get X+6=Y. Also after 5 years means (X+5)/(Y+5)=1/2. Solve both you get X=1,Y=7. So X+Y=8.

• x=y-6 and x+5:y+5=1:2.
  From these two equations x=1 and y=7.
  Sum of x & y=1+7=8years

• y-x=6
  and (x+5):(y+5)=1:2
  so y-2x=5
  so y=7 and x=1
  ans is 8

• given: X=Y-6
  (X+5):(Y+5)=1:2
  
  OR, (Y-6+5)/(Y+5) =1/2
  OR, Y=7
  
  SO, X=Y-6=7-6=1
  Y=7,X=1
  X+Y=8
  Ans:(b)

• x+6=y solving y we get y=7 and x=1 -->x+y=8
  5 years later
  x+5:y+5=1:2 ans :b
  y-1:y+5=1:2
• 13 years agoHelpfull: Yes(1) No(2)
• x+6=y
  5 yrs later x+5:y+5=1:2 hence x+y=8 ans:b
  y-1:y+5=1:2
  solving y=7 and x=1

• the ratio of ages=1:2.
  assuming the age of x is k,nd y iz 2k.
  so 5 yrs ago the age of x= k-5,nd y=2k-5.
  now 5 yrs ago x was 6 yrs younger than y,so we can write,
  2k-5=(k-5)+6
  so k=6.
  therefore x=6 nd y=12.
  the age total is 18

• X=6
  Y=6X
  (x+5)/(6x+5)=1:2
  x=.8
  y=4.8
  5.6==6

• x+6=y solving y we get y=7 and x=1 -->x+y=8
  5 years later
  x+5:y+5=1:2 ans :b
  y-1:y+5=1:2
