If the median of the data 30, 8, 7, 3, 17, 15, 21, 24, 29, 23 is x and the median of the data obtained by replacing 3 by 33 and 8 by 18 in the above data is y, then what is the difference between y and x ?
यदि आंकड़ों 30, 8, 7, 3, 17, 15, 21, 24, 29, 23 का माध्यक x है और इन आंकड़ों में 3 को 33 से तथा 8 को 18 से प्रतिस्थापित करने पर प्राप्त आंकड़ों का माध्यक यदि y है, तो y और x का अंतर क्या है?

Correct answer: (C) 33

Explanation

Sorted: 3, 7, 8, 15, 17, 21, 23, 24, 29, 30, so x = (17 + 21)/2 = 19. New data sorted: 7, 15, 17, 18, 21, 23, 24, 29, 30, 33, so y = (21 + 23)/2 = 22. y − x = 3.क्रमबद्ध करने पर: 3, 7, 8, 15, 17, 21, 23, 24, 29, 30, इसलिए x = (17 + 21)/2 = 19। नए आँकड़े क्रमबद्ध: 7, 15, 17, 18, 21, 23, 24, 29, 30, 33, इसलिए y = (21 + 23)/2 = 22। y − x = 3।
