A factory produces 7482, 8952, 6524, 8432 and 6562 units in 5 consecutive months. How many units should be produced in the sixth month, so that the average production for 6 months becomes 7200?

The average of 100 numbers is 40. If one of the numbers, 30, is replaced by 70 while keeping the other numbers same, what is the new average?

The arithmetic mean of 22.5, 56, 42.5, 2x + 1, x - 2, 3x, and 36 is 30. Find the value of x (where x > 0).
