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.You need to login to perform this action.
