Question

80% of the candidates were offered jobs. If 3 more had been given jobs, the
percent of employee would be 90%. Find how many candidates were
there?

Answer 1

Answer:

30

Step-by-step explanation:

let the number of candidates be X

  number of candidate were offered jobs = 80X/100

                                                                     =0.8X

3 more had been given job, then total candidate offered job = 90X/100

                                                                     =0.9X

since,        0.9X - 0.8X = 3

                 0.1X = 3

                 X = 3/0.1

                   X = 30

there are 30 candidates were there
