The eldest sibling received $261,000 the middle sibling received $99,000 and the youngest sibling received $87,000
Step-by-step explanation:
Let the youngest to receive x amount
So the eldest will receive 3x
The middle will receive x+12000
For equation for the total amount contributed by sibling shares
x+ 3x+x+12000=447000
5x+12000=447000
5x=447000-12000
5x=435,000
x=435,000/5 = $87000⇒Youngest
3x=3*87000=$261,000⇒Eldest
x+12000=87,000+12000=$99000⇒middle
