In an examination, 40% of the candidates failed. The number candidates who failed was 160. How many candidates passed the examination?

240 candidates

Step-by-step explanation:

40% candidates failed, i. e. out of every 100 candidates 40 failed.

40 failed 100 total students

1 failed 100/40 total students, given 160 failed therefore

160 failed (100/40) x 160 total students

Total students = (100/40) x 160 = 400

Number of candidates passed = (total candidates) - (total candidates failed)

                                                   = 400 - 160 = 240 candidates

i agree because i see the other persons thinking is clear
