Mean of 10 numbers is 58 so sum of 10 numbers is 580. One of them is 40 so the sum of the remaining nine is 540. So mean of the remaining nine is (their sum)/9 = 540/9 = 60 don't know if I'm understanding right but isn't it roughly 3.60
40% of 60 = 40/100 x 60 = 4/10 x 60 = 240/10 = 24
The sum of the numbers 1 to 39 = 39 x 40 ÷ 2 = 780 The sum of the numbers 1 to 60 = 60 x 61 ÷ 2 = 1830 Therefore the sum of the numbers 40 to 60 = 1830 - 780 = 1050
Take your pick; 10 and 20, 10 and 30, 10 and 40, 10 and 50, 10 and 60, 10 and 70, 10 and 80, 10 and 90, 20 and 30, 20 and 50, 20 and 70, 20 and 90, 30 and 40, 30 and 50, 30 and 70, 30 and 80, 40 and 50, 40 and 70, 40 and 90, 50 and 60, 50 and 70, 50 and 80 50 and 90, 60 and 70, 70 and 80, 70 and 90, 80 and 90.
LCM(30, 40, 60) = 120 GCF(30, 40, 60) = 10

Sum of 60, 40, 10, 10 = 120 Number of values = 4 So mean = 120/4 = 30

10
40, 50 and 60
factors of 120: 2, 3, 5, 6, 10, 12, 20, 24, 40, 60 composite numbers of 120: 6, 10, 12, 20, 24, 40, 60
The prime numbers between 40 and 60 are 41, 43, 47, 53 and 59. These sum to 243.
If you mean: 40, 50 and 60 then it is 10

10 and any multiple of 10 (20, 30, 40, etc) 20 and 30, 40 and 90, 60 and 70
40% of 60 = 40/100 x 60 = 4/10 x 60 = 240/10 = 24
