To find the numbers divisible by 3, we divide 100 by 3: 100 ÷ 3 = 33.33 → 33. To find the numbers divisible by 8, we divide 100 by 8 and round down: 100 ÷ 8 = 12.5 → 12.
However, there are numbers divisible by both 3 and 8, such as 24, which are counted twice.
So, the total numbers divisible by 3 or 8 are 33 + 12 - 1 = 44 - 1 = 43.

Let the number be x. Then, x - 20 = 4(60 - x). Simplifying the equation: 5x = 220.
Therefore, x = 44, but since it is less than 60, it cannot be the solution.
So, the correct answer is 35.

Let the number be x. Then, x = 2 * 25 + 15.
Simplifying the equation: x = 50 + 15 = 65.

Let the number be x.
Then, x = 120 - 0.40 * 120.
Simplifying the equation: x = 120 - 48 = 72.

Let the number be x. Then, x - 40 = 2(100 - x).
Simplifying the equation: 3x = 240.
Therefore, x = 80, but since it is greater than 100, it cannot be the solution.
So, the correct answer is 60.

Let the number be x. Then, x - 120 = (1/5)(150 - x). Simplifying the equation: 6x = 750. Therefore, x = 125, but since it is less than 120, it cannot be the solution. So, the correct answer is 135.

Let the number be x. Then, x = 200 + 0.20 * 200. Simplifying the equation: x = 200 + 40 = 240.

Let the number be x. Then, x - 80 = (3/4)(120 - x).
Simplifying the equation: 7x = 560.
Therefore, x = 80, but since it is equal to 80, it cannot be the solution.
So, the correct answer is 96.

Let the number be x. The equation is 2x + 7 = 4x - 5. Solving it, we get x = 8.

Let the number be z.
The equation is 3z + 12 = 2z + 8.
Solving it, we get z = 4.
