Consider a set of 11 numbers:
Value-I = Minimum value of the average of the numbers of the set when they are consecutive integers ≥ –5.
Value-II = Minimum value of the product of the numbers of the set when they are consecutive non-negative integers.
Which one of the following is correct?
Correct Answer :
Value-I = Value-II
Solution :
The correct answer is Value-I = Value-II.
Let us evaluate each of the two given values step-by-step.
Step 1: Calculate Value-I
We are given a set of 11 consecutive integers. Let these 11 consecutive integers be represented as:
where .
The average of 11 consecutive integers is simply the middle (6th) term, which is:
To find the minimum value of this average, we must take the smallest possible value for , which is .
Substituting :
Step 2: Calculate Value-II
We are given a set of 11 consecutive non-negative integers (i.e., integers ).
To minimize the product of these 11 consecutive non-negative integers, the smallest possible set starts at 0:
Since 0 is included in this set of numbers, the product of all 11 numbers in the set is:
Step 3: Compare Value-I and Value-II
Comparing the two calculated values:
Therefore, .
