(1) Jess has twice as much money as Katy and 2/3 as much as Erin.
(2) Jess has half the total amount of money that Katy and Erin have combined.
Let Jess have"J" money, Katy have "K"and Erin have "E"
Then,
E+J+K= 60
From statement 1 we can have
J=2K
Therefore, k=J/2
Similarly we have E= 3/2*J
So combining these we can find the value of J
From Statement 2 We have
J=1/2(E+K)
Therefore, E+K = J
So now we can find the value of J
So answer is D

The key thing to spot here is that both statements describe the amounts that each person has in relation to each other and since the total amount is provided in the original question stem, we know that both statements are sufficient.
