Question

the mean of 11 numbers is 42 if the mean of the first six number is 37 and that of the least 6number is 46find the 6 number

Answer 1

Answer:

36

Step-by-step explanation:

Mean of 11 numbers = 42

sum of 11 number = 42 * 11 = 462

Sum of first 6 Number ( 1-6) = 6 * 37

Sum of Last 6 Number (6-11) = 6 * 46

Sum of 12 Number where 6 number is repeated = 6*37 + 6*46 = 498

Sum of 12 Number  = Sum of 11 Numbers + Number 6

498 = 462 + Number 6

so Number 6 = 498 - 462 = 36
