\nA student asked to find the arithmetic mean of the numbers 4, 19, 17, 12, 34,16, 7, – 23,18, 21, 25, and x. Find the mean table 18. What should be the number in place of x.
\nAnswer:
\n\"1st
\n18 = \\(\\frac{196+x}{2}\\) = 216 = 196 + x
\n\u2234 x = 216 – 196 = 20<\/p>\n

Question 2.
\nThe average of 30 results is 20 and the average of other 20 results is 30. Find the average of results taken to gather.
\nAnswer:
\nGiven n1<\/sub> = 30, x\u03041<\/sub> = 20, n2<\/sub> = 20 , x\u03042<\/sub> = 30

Question 3.
\nIf the average of daily wages of workers of two factories is Rs. 53 and average wages to factory ‘A’ with 250 employees is Rs. 50. Find the average wage of factoring ‘B’ with 200 employees.
\nAnswer:
\nGiven X\u0304 = 53, X\u0304A<\/sub> = 50, nA<\/sub> = 250, X\u0304B<\/sub> = 7, nB<\/sub> = 200
\n\"1st
\ni.e., 200 X\u0304B<\/sub> = 23850 – 12500 = 11,350 \u2234 X\u0304B<\/sub> = \\(\\frac{11,350}{200}\\) = 56\/75
\n\u2234 Average wage of factory B = Rs. 56.75<\/p>\n

Question 4.
\nTen years ago the average age of the family of 4 members was 24 years. Two children have been born. The average age of the family is same to day. Find the present age of two children assuming that the children’s age differ by 2 years.
\nAnswer:
\n10 year ago x = 24, n = 4 \u2234 x = 24 \u00d7 4 = 96 year
\nIf 10 years ago, total age of 4 member = 96 year
\ntotal age of member now = (96 + 10 \u00d7 4) year = 136 year
\nTotal age of 6 member = 74 \u00d7 6 = 144 year
\ni.e., Sum of age of 2 children = 144 – 136 = 8 year
\nso x + x + 2 = 8 = x = 3 year
\n\u2234 The ages of children 3 and 4 year.<\/p>\n","protected":false},"excerpt":{"rendered":"
