SpletTherefore, x / 100 = 24. x = 2400. If 6 is added to all no.s then there would be 100 (6)s increase in the summation. New summation = x + 100(6) = 2400 + 600 = 3000. Now, if … SpletThe arithmetic mean of 100 observations is 24. So sum of all observations = 24*100 = 2400 Now, 6 is added to each of the observations, so the sum = 2400 + 100*6 = 3000 Then, each of them is multiplied by 2.5. So, the new sum of all observations = 3000*2.5 =7500 Hence new mean - 7500/100 = 75 So the correct answer is option B.
