    ₹5 notes. If the number of ₹10 notes is twice the number of ₹5 notes, how many notes of each type does he have?
    A ₹10 notes: 200, ₹5 notes: 100 Correct Answer Incorrect Answer
    B ₹10 notes: 400, ₹5 notes: 200 Correct Answer Incorrect Answer
    C ₹10 notes: 150, ₹5 notes: 100 Correct Answer Incorrect Answer
    D ₹10 notes: 120, ₹5 notes: 60 Correct Answer Incorrect Answer

    Solution

    Let the number of ₹5 notes be x. Then the number of ₹10 notes = 2x. Total value = 5x + 10(2x) = 5000. 5x + 20x = 5000, 25x = 5000, x = 200. Number of ₹5 notes = 200, ₹10 notes = 400. Answer: b) ₹10 notes: 400, ₹5 notes: 200.
