Got it??

Answer 2

Answer:

Thus, B is correct.

Explanation:

Given: 5 : 130 :: ____ : 350

It is analogy problem. We have to find out some relation between first two number 5 and 130 and it would be follow by next two number.

We can write ,

$130=5^3+5$

Any relation which follow, $a=n^2+n$ would be same analogy.

5 : 130 , 130 is add 5 to cube of 5.

Now we find same for ___ : 350

$350=x^3+x$

Here, x=7 will satisfy the relation.

At blank space 7 would be satisfy.

Thus, B is correct.
