Question

Consider the following three sets of numbers

A. 2, 5, 9

B. 1, 6, 10

C. 3, 4, 8

Which of the following represents correct ascending order of the averages of three sets A, B and C?

Choose the correct answer from the options given below

1. C < A < B
2. B < C < A
3. B < A < C
4. C < B < A

Answer 1

Correct Answer - Option 1 : C < A < B

Formula used:

Average = Sum of all the terms/Total number of terms

Concept used:

Ascending Order means number should be arranged in the increasing sequence

Calculation:

Average of the set A = (2 + 5 + 9)/3 = 5.33

Average of the set B = (1 + 6 + 10)/3 = 5.66

Average of the set C = (3 + 4 + 8)/3 = 5

Arranging in the ascending order, 5 < 5.33 < 5.66

∴ The correct sequence is C < A < B
