Here are the steps to compute the grades of the students:
Subject: English
Total: 150
Weights:
Written Work (WW): 40%
Performance Task (PeTa): 50%
Quarterly Assessment (QA): 10%
Aquino:
WW: 34/40 * 40% = 13.6
PeTa: 36/60 * 50% = 18
QA: 56/60 * 10% = 9.2
Total: 13.6 + 18 + 9.2 = 40.8
Grade: 40.8/150 * 100 = 27.2, which rounds to 27
Cayetano:
WW: 36/40 * 40% = 14.
