Answer 2

Answer:

The missing number is 117.33.

Step-by-step explanation:

• A ratio written as a/b or a:b, where $b\ne 0$, gives a comparison between two quantities a and b.

• When two ratios are equal, then it is said to be in proportion, and written as a : b :: c : d.
• The first and last terms (a & d) are called the extremes, and the middle terms (b & c) are called the means.

• In a proportion, the product of the means is equal to the product of the extremes. This property is called means-extremes property.

Let us apply this property to solve the problem.

Given 6 : 64 :: 11 :

Let the other number be $x$.

Then 6 and x are the extremes, and 64 and 11 are the means.

Thus, $6\times x=64\times 11$

$\implies x=\dfrac{64\times 11}{6} =\dfrac{704}{6}=117.33$  

Therefore, the missing number is 117.33.

There is no correct answer in the options given.

If the symbols used between the numbers are ignored, then just see the logic with the numbers.

6 becomes 64, if we add 2 and square it i.e., $(6+2)^{2} =64$

Similarly take 11, add 2 and square it.

The result is $(11+2)^{2} =13\times 13=169$

So, the correct answer is option 2.
