Hints




Click a Tab to reveal the Hint.

US Version

Try comparing the two tables that have the most similar items.

UK Version

Try comparing two tables which have similar items.

US Version

Calculate the total bill for each table in terms of cups of tea. Start with tables 1 and 3.

UK Version

Try to work out how much the total bill for each table is in terms of cups of tea.


Start by comparing tables 1 and 3.

Tables 1 and 3 have the same amount of juice, so ignore the juice in the comparison.

That leaves you with a cup of tea and a plate of toast on table 1, and three cups of tea on table 3.

You can then work out that one plate of toast costs the same as two cups of tea.

US Version

You've have learned that one plate of toast costs the same as two cups of tea, so now take a look at table 2.

If you replace the toast with tea, you'll have four cups of tea on the table. What must the last item on table 4 be?

UK Version

Now you know that a portion of toast costs the same as two cups of tea, have a look at table 2. If you replace the toast with its equivalent value of tea, you'll have four cups of tea on the table. So now you know what the last item on table 4 must be!


Solution

Incorrect

Too bad!

US Version

Maybe you should make yourself a cup of tea to help you concentrate.

UK Version

Why not have a nice cup of tea and think it over?

Correct

Tea-riffic!

US Version

A cup of tea is correct!

If you look at table 1 and 3, you can deduce that a plate of toast costs the same as two cups of tea. From here, you can figure out that the total price of the food ordered by each table is the same as the cost of four cups of tea.

UK Version

The answer is item A, a cup of tea.

If you look at tables 1 and 3, you can deduce that a plate of toast costs the same as two cups of tea. Applying that knowledge, you should be able to work out that the total value of items on each table is the same as four cups of tea.
