    In an examination, the number of students who passed and the number of those who failed were in the ratio of 25: 4. If five more students had appeared and the number of failed students was 2 less than earlier, the ratio of passed to failed students would have been 22:3; What is the number of students who appeared for the examination?

    A)  145                             

    B)  150     

    C)  155                 

    D)         180                 

    E)  190

    Correct Answer: A

    Solution :

    Let the number of students who appear be (25x + 4x) = 29x Bank of Baroda Now, Appeared    Passed      Failed 29x   25x         4x Now, 29x + 5   (29x +5)      4x - 2 - (4x - 2) Then. \[\frac{(29x+5)-(4x-2)}{4x-2}=\frac{22}{3}\] or. \[\frac{25x+7}{4x-2}=\frac{22}{3}\] or, \[88x-44=75x+21\] or, 13x = 21 + 44 = 65 \[\therefore \]  x = 5 Hence total number of appeared students = 29x = 29\[\times \]5 = 145 Note: In such questions, we do not need to solve in first attempt. First check the given choices and select the choice where no. of students in perfectly divisible by 25 + 4 == 29. In this case only option (1) 145 is such number so it is our answer.
