K2,k,k+1,k+3 Mean: 4k+2 /4 =k + 1/2 Median : k+k+1 /2=k + 1/2 The ratio is 1. Option A Posted from my mobile device

1) organize the values  K  2 , k , K+1, K+3 2) Plug 10 in for K  8,10,11,13 3) Set up ratio mean / median 4) find mean & median  mean = 10 + 11 = 21  Median = 10 + 11 = 21 5) Plug back mean and median into ration  21/21 Answer A = 1

Solution GivenIn this question, we are given that • Positive integers k, k + 1, k – 2, and k + 3 To findWe need to determine • The ratio of the mean and median of the given numbers Approach and Working outMean of the numbers = ¼ (k + k + 1 + k – 2 + k + 3) = k + 0.5 Numbers in ascending order: k – 2, k, k + 1, k + 3 Hence, the median = ½ (k + k + 1) = k + 0.5 • Therefore, the required ratio = (k + 0.5)/(k + 0.5) = 1 Thus, option A is the correct answer. Correct Answer: Option A

The main idea to solve this question is arranging the terms in ascending order for finding the Median.Doing mistake in this will give a wrong answer.
