  • Question
  • A fruit seller has a crate of apple containing 1 bruised apple for every 40 apples in the crate, If 3 out of every 4 bruised apples are considered unsaleable and there are 9 unsaleable apples in the crate, then how many apples are there in the crate?


  • Options
  • A. 500
  • B. 390
  • C. 632
  • D. 480

  • Correct Answer
  • 480 

    Explanation

    Let total number of apples in the crate = a
    Then, number of bruised apples = a/40 .
    Number of unsaleable apples
    since 4 bruise apples containing 3 unsaleable apples.
    therefore 1 bruise apples will contain 3/4 unsaleable apples
    hence a/40 bruise apples will contain 3/4 x a/40 unsaleable apples
    = 3/4 x a/40 = 3a/160
    According to the question.
    3a/160 = 9
    ? a = 9 x 160/3
    a = 3 x 160 = 480
