Question

In the given proportion $9:3::36:12$ extremes are

• A. $9,3$
• B. $36,12$
• C. $3,36$
• D. $9,12$

Answer 1

Answer: (D)

If the two ratios are equal then they are said to in Proportion.

i.e., If $\frac{a}{b}=\frac{c}{d}$ then $a:b::c:d$

Here, $a,d$ are extremes and $b,c$ are the means.

Now,

In $9:3::36:12$

$9,12$ are extremes and $3,36$ are the means.

Hence, Option D is correct.
