For a journey the cost of a child ticket is 1/3rd of the cost of an adult ticket. If the cost of the ticket for 4 adults and 5 children is Rs. 85, what is the cost of a child ticket?

• cost of 1 child=C
  cost of 1 adult=A
  C=1/3 A =>A=3C
  4A+5C=85
  => 12C+5C=85
  => 17C= 85
  =>C=5 (ans)

• Let
  Adult's fare= 3x
  then, child's fare= x
  also, 4*3x+5*x=85 => 17x=85 => x=5
  so, A's fare=15 and C's= 5

• 5rs
  c=a/3
  4a+5c=85 solving those equations we get 5 rs

• 1/3a=c
  4a+5c=85
  4a+5(1/3)=85
  a=255/17
  a=15 i.e adult =15
  child=1/3*(15)=15/3=5

• let x be the cost of an adult ticket...so
  4x+(5*.33x)=85
  so cost of a child ticket=5

• 4x+5x/3=85
  x=15
  child ticket will be of rs. 5

• cost of child=x.
  cost of adult=y.
  given x=y/3 and 4y+5x=85.
  sub x=y/3 in 4y+5x=85,
  so 4y+5*y/3=85.
  after solving 17y=85,y=15.
  so x=15/3 =5

• let 'a' be adult age,'c' be child age
  c=(1/3)a
  4a+5c=85
  on solving two equations
  a=15
  c=5

• 4x+(5/3)x=85
  then x= 15
  therefore the cost of a child ticket is 5

• let the cost of adult ticket is X. so child ticket is X/3.
  now 4X+(5/3)X = 85 so X=15 for adult.
  now child ticket is 5.

• cost of a child ticket is Rs. 5 and cost of a adult ticket is Rs. 15
  So (4*15) +(5*5)=85..

• C=A/3
  4A+5C=85
  4A+5A/3=85
  A=15
  C=5

• suppose adults ticket cost=x
  then child's ticket cost=x/3
  and 4x+5x/3=85
  so x=15
  so cost of a child's ticket=x/3=5
  so 5 is the ans.

• 4x+5x/3=85. 17x/3=85. X=15. So childticket=5

• A=3C
  4A+5C=85
  Sub A=3C
  c=5

• x,(x/3)
  4x+(5x/3)=85
  x=15
  (x/3)=5

• Assume cost of child ticket be X and adult ticket be Y
  
  Given child ticket = 1/3 rd of adult ticket
  
  X= 1/3Y therefore Y= 3X
  
  and given Total cost for tickets for 4 adults and 5 children is 85
  
  5X + 4Y = 85
  
  put Y= 3X from the above equation and solve for X
  
  solving we get X = 5
  
  cost of child ticket = Rs 5

• child = 1/3x
  4x + 5/3 x = 85
  12x+5x = 255
  x= 5
  child = 25
