A sum of \(\$200,000\) from a certain estate was divided among a spouse and three children. How much did the youngest child receive?
A sum of \(\$200,000\) from a certain estate was divided among a spouse and three children. We need to determine exactly how much the youngest child received.
For sufficiency, we need to find one unique value for the youngest child's share. If multiple distributions are possible, we don't have sufficiency.
We have 4 unknowns (spouse's share, oldest child's share, middle child's share, youngest child's share) that must sum to \(\$200,000\). To find one specific share uniquely, we need enough relationships to eliminate all ambiguity about how the money was divided.
Statement 1: The spouse received 1/2 of the sum from the estate, and the oldest child received 1/4 of the remainder.
Since we have \(\$75,000\) to split between two younger children, let's see if the youngest child could receive different amounts:
All three scenarios are mathematically valid since they all total \(\$75,000\). Statement 1 doesn't tell us how to split this \(\$75,000\) between the two younger children.
Since we can identify multiple possible values for the youngest child's share (\(\$25,000\), \(\$50,000\), or \(\$37,500\)), Statement 1 is NOT sufficient.
[STOP - Not Sufficient!] This eliminates choices A and D.
Now let's forget Statement 1 completely and analyze Statement 2 independently.
Statement 2: Each of the two younger children received \(\$12,500\) more than the oldest child and \(\$62,500\) less than the spouse.
This statement gives us two crucial pieces of information:
Since both expressions equal the same amount (what each younger child received), we can write:
Oldest child + \(\$12,500\) = Spouse - \(\$62,500\)
Rearranging: Spouse = Oldest child + \(\$75,000\)
Now we can express everyone's share in terms of the oldest child's share (let's call it "O"):
Since all shares must sum to \(\$200,000\):
\(\mathrm{O} + (\mathrm{O} + \$75,000) + (\mathrm{O} + \$12,500) + (\mathrm{O} + \$12,500) = \$200,000\)
Simplifying: \(4\mathrm{O} + \$100,000 = \$200,000\)
Therefore: \(4\mathrm{O} = \$100,000\), which means \(\mathrm{O} = \$25,000\)
This gives us exactly one possible distribution:
Statement 2 provides enough constraints to determine exactly one distribution. The youngest child received \(\$37,500\).
Statement 2 is sufficient.
[STOP - Sufficient!] This confirms our answer is B.
Since Statement 1 alone is not sufficient but Statement 2 alone is sufficient, the answer is B.
Answer Choice B: "Statement 2 alone is sufficient, but Statement 1 alone is not sufficient."
