Table: Office supplies bought — 12 reams of bond paper at ₱250 each, 30 ballpens at ₱15 each, 5 staplers at ₱180 each. If the price of each ream of bond paper rises by 10%, how much more will the 12 reams cost?
Correct answer: B. ₱300
The 12 reams cost ₱3,000, and 10% of ₱3,000 is ₱300. Equivalently, each ream rises by ₱25 and 12 × ₱25 = ₱300. The new total for the bond paper would be ₱3,300.
