Answer:
<h2>Island A, B and C has 10, 5 and 7 houses respectively.</h2>
Step-by-step explanation:
Let, the three islands A, B and C has a, b and c houses respectively.
According to the question, a + b = 15; a + c = 17; b + c = 12; a + b + c = 22.
Adding [ a + b = 15; a + c = 17]-these two, we get,
.
Now,

<em>Plane figures</em> are shapes with <u>straight </u>sides. Considering the <em>movement</em> to be <em>lower</em> than the initial path, there are eleven (11) <u>paths</u> from A to B.
A <em>plane figure</em> is given shape with <u>straight</u> sides. And these <em>sides </em><u>connect</u> each edge of the figure one to another. Examples are triangles, quadrilaterals, polygons, etc.
A path is a <em>connection</em> or <u>link</u> between two <em>reference </em>points. This could be a <u>footpath</u> or a <u>motorable</u> path or <u>other</u> forms of the path.
Considering the given <em>plane figure</em> in the question, it can be observed that the <u>total</u> <u>number</u> of paths from A to B with respect to the given condition is eleven.
