The given by question:
985 : 874 : : 763 : ?
We have to find, the value of missing number (?).
Solution:
We have:
985 : 874
= 985 - 874
= 111
Similarly:
763 : ?
763 - ? = 111
⇒ ? = 763 - 111
⇒ ? = 652
∴985 : 874 : : 763 : 652
Thus, the required "option is d) 652".
Given:
985 : 874 :: 763 : ?
To find:
The term of the second pair.
Solution:
From given, we have the data as follows.
985 : 874 :: 763 : ?
Consider the first pair to understand the relation between the terms.
985 : 874
= 985 - 874
= 111
The relation between the terms is such that, when we substract both the terms, we should obtain the result as 111, we will get the series.
The same we will consider to form the second term of the second pair.
763 : ?
763 - ? = 111
? = 763 - 111
? = 652
763 : 652
∴ 985 : 874 : : 763 : 652
