Question

Several kettles are shown below. What is the total number of usable kettles that are designed to store and pour hot water?

Hint:

Usable here means the kettle needs BOTH a pour spout and a lifting handle. Check the whole set once for missing spouts, then check again for missing handles, instead of judging each kettle all at once - that way a decorative pot or plain mug will not slip through as usable.

Answer 1

Correct Answer: 13

Step 1: Analyze the kettles.
The image shows several kettles, but not all of them are usable for storing and pouring hot water. To identify the usable kettles, we look for those that have a spout and are designed for pouring water. Some kettles may be decorative or non-functional.
Step 2: Count the usable kettles.
By analyzing the image and identifying the kettles that have a handle and a spout, we count a total of 13 usable kettles. These are the kettles designed to store and pour hot water.
Step 3: Conclusion.
Thus, the total number of usable kettles is \( \boxed13 \).

Answer 2

Concept:

• A kettle only counts as usable for storing and pouring hot water if it satisfies two separate conditions at once: a spout to pour water out, and a handle to lift and hold it safely.
• Instead of judging every silhouette all at once (easy to make a mistake on), it is more reliable to check one condition at a time across the whole set, eliminating anything that fails either test.

Step 1: Label the grid systematically.
Go through the kettles row by row, left to right, giving each one a temporary label so that none is skipped or checked twice while comparing it against the two conditions below.

Step 2: Eliminate icons with no pour spout.
A few of the silhouettes are plain jugs, mugs, or lidded pots with no projecting spout. Water could only be poured from these by tilting the whole rim, which is not what a kettle is designed for, so mark these out first.

Step 3: Eliminate icons with no lifting handle.
Of the icons that survive Step 2, check each one for a clear arched or side handle that keeps the hand away from the hot body. Any icon that has a spout but no separate handle is eliminated at this stage too.

Step 4: Count what remains.
Every silhouette that was not eliminated in Step 2 or Step 3 has both a spout and a handle, so it qualifies as a kettle genuinely designed to store and pour hot water. Counting these gives the total.

Final Answer: 13
