Question

in an examination 35% of the candidates failed in the mathematics and 25% in English if 10% failed in both mathematics and English then how much percent of passed in both the subjects​

Answer 1

Answer:

Step-by-step explanation:

First, 25+35–10=50% who failed one exam or the other, or both. This leaves us with 50% who didn’t fail any exam, so they passed both.

Answer 2

Answer:

50% candidates passed in both the subjects​

Step-by-step explanation:

Candidates failing in Mathematics = 35%

Therefore, the candidates passing in Mathematics = 100% - 35%

                                                                                    = 65%

Candidates failing in English = 25%

Therefore, the candidates passing in English = 100% - 25%

                                                                           = 75%

Candidates failing in both = 10%

Therefore, the candidates passing in both = 100% - 10%

                                                                      = 90%

Therefore, the percentage of candidates passing in both the subjects =

Passed in English + Passed in Mathematics - Passed in both

= 75% + 65% - 90%

= 140% - 90%

= 50%

Therefore, 50% candidates have passed in both the subjects​
