No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Let a pen be p and a book b. Then 2p + 3b = 230 and 4p + 5b = 400. Doubling the first gives 4p + 6b = 460, and subtracting the second leaves b = 60. Substituting back gives 2p = 230 − 180 = 50, so p = 25.
