The question was if the ratio of age of two persons is 5:6,sum of present age is 33,then in how many years the ratio of their age becomes 7:8?

• answer=6 years
  5x+6x=33
  x=3
  presnt ages are (5*3)=15,(6*3)=18
  after y years-
  ratio will be 7:8 so,
  15+y/18+y=7/8
  y=6.

• in 6 years..
  now age is 15 and 18.
  in six years age will be 21 and 24.
  i.e 7:8
• 9 years agoHelpfull: Yes(12) No(0)
• 5X+6Y =33
  5*3+6*3=33
  After that,
  7*3+8*3=45
  i.e, in ration 7:8
  45-33=12
  12/2=6
  after 6 years ratio becomes 7:8
  12/
• 9 years agoHelpfull: Yes(5) No(1)
• 1part=33/11=3
  ratio is increased by 2part in both numerator and denominator
  so the answer is 6.

• ans :6yr
  5x+6x=33
  x=33/11=3
  5*3:6*3=15:18
  similarly
  7*3:8*3

• present ages=5:6 that is 5x+6x=33 where we get x=3
  [lacing x=3 in ratios 5x=15,6x=18
  years to go to get a ratio 7:8 is 6
  adding 6 years to 15,18 we get the ages 21,24.
  the ratio of 21,24 is 7:8
• 9 years agoHelpfull: Yes(0) No(0)
• 6 is the ans
  
• 9 years agoHelpfull: Yes(0) No(0)
• 6 yrs
  x+y=33
  and x:y=5:6
  solving two eqns:
  x=15 and y=18
  now let z be the years then
  (x+z)(y+z)=78
  on solving z=6yrs

• todays ages are 15 &18
  after 6 years ,it will be 21 &24
• 9 years agoHelpfull: Yes(0) No(0)
• 6 years.
  given let x+y=33
  let us assume the present ages are (5*3)=15, (6*3)=18 which are 5:6 ration.
  now we have to calculate after how many years the ration must be 7:8.
  now, 7*3:8*3=> 21:24
  21-15=6
  the Answer is 6 years.
• 9 years agoHelpfull: Yes(0) No(1)
• after 6 years
  5:6 sum is 11
  means 1 is 15 and other 18
  hence the ratio chages two in 6 years

• ans:2
  assume that
  
  p1 age is=21
  p2 age is =16
  
  p1+p2=37
  
  37-33=4years
  
  so after two years we will add 2years for both of them

• 9 years agoHelpfull: Yes(0) No(0)
• 5x+6x=33
  x=3
  5x/6x+?=7x/8x

• The given ratio of the two person is 5:6 and the sum age is 33. So take the one person age as x and the another person age is 33-x. then we have to find x.
  In the ratio of age we can calculate it as
  x/33-x=5/6
  then we will get x=15.
  the first person is 15. and the second person is 18.
  then they asked how many years the ratio age becomes 7:8.
  To find we have to add years to calculate this present ages. We take x for how many years should add to the present ages.
  15+x/18+x=7/8.
  And the ans is 6 years
• 9 years agoHelpfull: Yes(0) No(0)
• X/Y = 5/6 AND X+Y= 33,SO X=5/6Y
  5/6Y+Y= 33,SO Y=18,X=15
  15+Z/18+Z= 7/8 SO Z=6

• 6 years...
  P: 15+18=33
  after 6 years= 21:24== 7:8
• 9 years agoHelpfull: Yes(0) No(0)
• In 6 years
• 9 years agoHelpfull: Yes(0) No(0)
• Their ages will be 5x,6x.
  Sum of ages11x=33,then x=3
  (15+x)/(18+x)=7/8,then x=6. therefore after 6 years
• 9 years agoHelpfull: Yes(0) No(0)
• 5x+6x=33
  x=3
  present age is 15 and 18
  in 6 years the ratio of theor age become 7:8
• 9 years agoHelpfull: Yes(0) No(0)
• Taketwo persons are a&b.sum of their ages is 33,so a+b=33 &a/b=5/6.so present age of a is 15 and b is 18.so by adding 6 years we get the ratio 7:8 i.e;(15+6)/(18+6)=21/24=7:8
  so 6years is the correct answer

• let present age is X
  5X+6X=33--->11X=33--->X=3 i.e. 15,18;
  After 3 years their ages become 21,24 i.e. required answer(after 3 years)
• 9 years agoHelpfull: Yes(0) No(0)
• its 2 years..
• 9 years agoHelpfull: Yes(0) No(0)
• 6 years
  
  11x=33 // (5x+6x)
  15+6 = 21
  18+6 = 24

• Answer is 6 years.
  Because the present age based on the ratio(5:6) are15 and 18 respectively. So that after 6 years the ratio will be 7:8
• 8 years agoHelpfull: Yes(0) No(0)
• 6 years is the answer.
  present age is 5:6 that is 15 and 18.total age is 33,after six years the ratio will be 7:8,so answer is 6
• 8 years agoHelpfull: Yes(0) No(0)
• 5x+6x=33
  so x =3
  7x+8x=15x=45
  45-33=12
  so after 6yrs
  
• 8 years agoHelpfull: Yes(0) No(0)
• 
  5x+6x=33
  x=3
  presnt ages are (5*3)=15,(6*3)=18
  after y years-
  ratio will be 7:8 so,
  15+y/18+y=7/8
  y=6.
  ans=6
• 8 years agoHelpfull: Yes(0) No(0)
• 6 years
  5x+6x=11x
  so x=3
  so we substitute 3 in x then the first person have 5*3=15, 6*3=18
  so after y years 15+y/18+y=7/8
  y=6
• 8 years agoHelpfull: Yes(0) No(0)
• And:6 years
  Explanation:
  5x+6x=33 then x=3 so present ages are 15 and 18
  Add 6 to present age the ratio will become 7:8
• 6 years agoHelpfull: Yes(0) No(0)
• after 6 years the ratio between there ages will be 7:8
• 5 years agoHelpfull: Yes(0) No(0)
