.X is 6 years younger to Y. X's father is a businessman who invested 10000 at 8% rate of interest and obtained his amount after 10 years. Y's father is a job holder who invested around 20000 at 2% rate and obtained his amount after 20 years. Now compounding, both of them get around Rs. A. 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's father is 30 years more than X. After 20 years, again X's mother asks X's father to purchase a LCD TV which costs around 45000. What is the age of X and Y together?
(a) 12
(b) 8
(c) 18
(d) 6

• let y age is A
  than x age will be A-6
  
  After 5 years
  y age will be A+5
  x age will be A-6+5=A-1
  
  now given A-1/A+6=1:2
  
  solve this u will get A=7 so age of y is 7years
  and as given in the question X is 6 years younger than y so age of X is 1 years
  
  ans is 8

• ans- 8
  present age - x & y yrs & x=y-6
  after 5 yrs- x+5/y+5 = 1/2
  y-6+5/y+5= 1/2
  which gives y= 7yrs & x=1yrs.
  Rest is irrelevant.

• X=x Y=x+6
  after 5 year
  x+5/x+11=1/2
  we get x=1
  y=7
  x+y=1+7=8

• yes it's 8
• 11 years agoHelpfull: Yes(4) No(0)
• present age - x & y yrs & x=y-6
  after 5 yrs- x+5/y+5 = 1/2
  y-6+5/y+5= 1/2
  which gives y= 7yrs & x=6yrs.
  Rest is irrelevant.

• yes ans is 8
• 11 years agoHelpfull: Yes(1) No(0)
• Y-6=X
  Y+5/X+5=2/1
  then solve we get y=7 and x=1
  so sum is 7+1=8
