Question
Out of the total candidates who
appeared for an interview consisting of only a GD round and a Technical round: 65% of candidates passed the GD round. 48% of candidates passed the Technical round. 30% of candidates passed both rounds. What % of candidates failed in both the GD round and the Technical round?Solution
ATQ,
Let total number of candidates who appeared for the interview = ‘100x’ Number of candidates who passed in both GD round and Technical round = 0.30 × 100x = ‘30x’ Number of candidates who passed only in Gd round = 0.65 × 100x – 30x = ‘35x’ Number of candidates who passed only in Technical round = 0.48 × 100x – 30x = ‘18x’ Number of candidates who failed in both GD round and Technical round = 100x – 30x – 35x – 18x = ‘17x’
