Question

So far this year, Mr. and Mrs. Dufaa have paid what percent of their annual home expenses?

(1) So far the Dufaas have paid 1⁄2 of their annual electricity bill, 1⁄2 of their annual gas bill, 1⁄4 of their annual water bill, and 3⁄4 of their annual trash bill.
(2) The Dufaas’ annual home expenses include four items: electricity, gas, water, and trash removal.

Kingsman · Answer

IMO the answer is E. We need to know what proportion does each expense such as: electricity, gas, water and trash removal composed of the total expenses of Dufaa's family

MHI · Answer

Answer:  E

Both statements are insufficient. The bill is not equally divided among the 4 categories.

GSBae · Answer

If you're trying to figure out if this is enough information, try to think in extremes: If the electric bill is huge, and all the other items are small, then they've paid about ~1/2 of their total bills. On the other hand, if their trash bill is huge and all the other items are small, then they've paid ~3/4 of their total bills. We can't say for sure without the exact percentages.

Look at other examples of 'weighted average' problems.
