Question

If in a room 10 beds can be placed, then how many beds can be placed if the size of the room is halved?

• A. 5

Answer 1

The correct option is A 5
Let the number of beds in half the size of the room be 'c'.

Writing the given statement in proportion, we have,
$10:1::c:\frac{1}{2}$

We know, product of means = product of extremes
$\Rightarrow 1\times c=10\times \frac{1}{2}$
$\Rightarrow c=5$

Number of beds that can be placed if the room is halved = 5
