Question 1.
\nFind Arithmetic Mean of the following.
\n(i) 4, 5, 11, 8
\nAnswer:
\nGiven data: 4,5, 11, 8.
\nSum of observations = 4 + 5 + 11 + 8 = 28
\nNumber of observations = 4
\n\u2234 Arithmetic Mean = \\(\\frac{\\text { Sum of observations }}{\\text { Number of observations }}\\) = \\(\\frac{28}{4}\\) = 7.<\/p>\n

\"AP<\/p>\n

(ii) 10, 15, 21, 12, 17
\nAnswer:
\nGiven data: 10, 15, 21, 12, 17
\nSum of observations 10 + 15 + 21 + 12 + 17 = 75
\nNumber of observations = 5
\n\u2234 Arithmetic Mean = \\(\\frac{\\text { Sum of observations }}{\\text { Number of observations }}\\) = \\(\\frac{75}{5}\\) = 15<\/p>\n

(iii) \\(\\frac{1}{4}, \\frac{1}{2}, \\frac{3}{4}, \\frac{3}{2}, \\frac{5}{4}\\)
\nAnswer:
\nGiven data: \\(\\frac{1}{4}, \\frac{1}{2}, \\frac{3}{4}, \\frac{3}{2}, \\frac{5}{4}\\)
\nSum of observations = \\(\\frac{1}{4}+\\frac{1}{2}+\\frac{3}{4}+\\frac{3}{2}+\\frac{5}{4}\\) = \\(\\frac{1+2+3+6+5}{4}\\) = \\(\\frac{17}{4}\\)
\nNumber of observations = 5
\n\u2234 Arithmetic Mean = \\(\\frac{\\text { Sum of observations }}{\\text { Number of observations }}\\)
\n= \\(\\frac{\\frac{17}{4}}{5}=\\frac{17}{4} \\div \\frac{5}{1}=\\frac{17}{4} \\times \\frac{1}{5}=\\frac{17}{20}\\)
\n\u2234 Arithmetic Mean = \\(\\frac{17}{20}\\)<\/p>\n

Question 2.
\nAmounts donated by eight students to ‘NIVAR’ cyclone effected people are \u20b9300, \u20b9450, \u20b9700, \u20b9650, \u20b9400, \u20b9750, \u20b9900 and \u20b9850. Find the Arithmetic Mean of amounts donated.
\nAnswer:
\nGiven data, \u20b9300, \u20b9450, \u20b9700, \u20b9650, \u20b9400, \u20b9750, \u20b9900 and \u20b9850.
\nSum of observations = 300 + 450 + 700 +650 +400 + 750 + 900 + 850 = 5000
\nNumber of observations = 8
\n\u2234 Arithmetic Mean = \\(\\frac{\\text { Sum of observations }}{\\text { Number of observations }}\\) = \\(\\frac{5000}{8}\\) = \u20b9625
\n\u2234 Arithmetic Mean of amount donated = \u20b9625<\/p>\n

Question 3.
\nThe number of passengers who travelled in APSRTC bus from Eluru to Rangapuram in 5 trips in a day are 35, 42, 28, 41 and 44. What is the average of number of passengers travelled per trip ?
\n\"AP
\nAnswer:
\nGiven data are 35, 42, 28, 41, 44.
\nSum of observations = 35 + 42 + 28 + 41 + 44 = 190
\nNumber of observations = 5
\n\u2234 Arithmetic Mean (or) Average = \\(\\frac{\\text { Sum of observations }}{\\text { Number of observations }}\\) = \\(\\frac{190}{5}\\) = 38
\n\u2234Average of number of passengers travelled per trip = 38.<\/p>\n

Question 4.
\nFind Arithmetic mean of factors of 24.
\nAnswer:
\nFactors of 24 are 1, 2, 3, 4, 6, 8, 12, 24.
\nSum of (factors) observations = 1 + 2 + 3 + 4 + 6 + 8+ 12 + 24 = 60
\nNumber of observations = 8
\n\u2234 Arithmetic Mean = \\(\\frac{\\text { Sum of observations }}{\\text { Number of observations }}\\) = \\(\\frac{60}{8}\\) = 7.5
\n\u2234 Arithmetic Mean of factors of 24 is 7.5<\/p>\n

Question 5.
\nFind the Arithmetic Mean of x, x + 1 and x + 2.
\nAnswer:
\nGiven data x, x + 1, x + 2.
\nSum of observations = x + x + 1 + x + 2 = 3x + 3
\nNumber of observations = 3
\n\u2234 Arithmetic Mean = \\(\\frac{\\text { Sum of observations }}{\\text { Number of observations }}\\)
\n= \\(\\frac{3 x+3}{3}\\) = \\(\\frac{3(x+1)}{3}\\)
\n\u2234 Arithmetic mean = x + 1<\/p>\n","protected":false},"excerpt":{"rendered":"
