Question 145Asked in Bihar STET 2025 Paper II Computer Science, 7 Nov 2025, Shift 1 (9:00 AM)

If the median of the data 30,8,7,3,17,15,21,24,29,23 is x and the median of the dataयदि आंकड़ों 30,8,7,3,17,15,21,24,29,23 का माध्यिका x है और इन आंकड़ों में 3 को 33 से तथा 8 को

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 माध्यिका x है और इन आंकड़ों में 3 को 33 से तथा 8 को 18 से प्रतिस्‍थापित करने पर प्राप्‍त आंकड़ों का माध्यिका यदि Y है,तो Y और X का अंतर क्‍या है?

Correct answer: (B) 33

Explanation

Sorted: 3,7,8,15,17,21,23,24,29,30, so x = (17+21)/2 = 19. After the replacement: 7,15,17,18,21,23,24,29,30,33, so y = (21+23)/2 = 22. The difference y − x is 3.क्रमबद्ध: 3,7,8,15,17,21,23,24,29,30, इसलिए x = (17+21)/2 = 19। प्रतिस्थापन के बाद: 7,15,17,18,21,23,24,29,30,33, इसलिए y = (21+23)/2 = 22। अंतर y − x = 3।
