  • Question
  • The number of oranges in three baskets are in the ratio of 3 : 4 : 5. In which ratio the no. of oranges in first two baskets must be increased so that the new ratio becomes 5 : 4 : 3?


  • Options
  • A. 1:3
  • B. 2:1
  • C. 3:4
  • D. 2:3

  • Correct Answer
  • 2:1 

    Explanation

    Let,   B1 : B2 : B3 = 3x : 4x : 5x 

     

    again  B1 : B2 : B3 = 5y : 4y : 3y

     

    Since there is increase in no.of oranges in first two baskets only, it means the no. of oranges remains constant in the third basket

     

    Therefore,   5x = 3y

     

    Hence    3x : 4x : 5x   =>    9 y 5 : 12 y 5 : 15 y 5  = 9y:12y:15y

     

    and       5y : 4y : 3y   =>   25x : 20x : 15x

     

    Therfore, increment in first basket = 16

     

    Increment in second basket = 8

     

    Thus, required ratio = 16/8 = 2:1
