In an examination, equal number of candidates from both state A and state B appeared. 15% candidates passed from state A and 25% candidates passed from state B. If 40 more candidates from state B were selected than state A, what is the total number of candidates who appeared for the examination? Correct Answer 800

Let the number of candidates who appeared from both the states be x.

Number of candidates who passed from state A = 15x/100

Number of candidates who passed from state B = 25x/100

According to the question, 40 more candidates passed from state B.

Thus, 25x/100 - 15x/100 = 40

⇒ x = 400

⇒ 400 candidates appeared from each state.

∴ Total 800 candidates appeared for the exam.
