  1. Number of candidates who failed in Maths `= 43%`
    Number of candidates who failed in both Physics and Maths ` = 14%`
    `:. `Number of candidates who failed only in Maths ` = 43-14 = 29%`
    It means the number of candidates who passed only in Physics will also be equal to `29%`.
    Let `x` is the number of totals candidates. Then,
    `x**29/100 = 580=> x = 20**100 = 2000`
    So, total number of candidates are `2000`.
