INSTITUTED: A,B, & C
A: PIANO OF 10,000
B: DIAMOND RING OF 30,000
A: 100,000 = PIANO 10,000 + 90,000
B: 100,000 = RING 30,000 + 70,000
C: 100,000
A, B, and C were instituted heirs to an estate totally valued at P300,000 but it was specifically provided that the piano (in the estate) worth P10,000 should go to A, and a diamond ring (also in the estate) worth P30,000 must go to B. How will the entire estate be divided?
