1. A number when divided by 5 is decreased by 40. Find the number?

45 50 55

Step-by-Step Logic:
1. Let the number be x. 2. The new number is x / 5. 3. Equation: x - (x / 5) = 40. 4. Multiply by 5: 5x - x = 200. 5. 4x = 200, so x = 50.

2. A number when divided by 3 is decreased by 20. Find the number?

25 30 35

Step-by-Step Logic:
1. Equation: x - (x / 3) = 20. 2. Multiply by 3: 3x - x = 60. 3. 2x = 60, so x = 30.

3. A number when divided by 10 is decreased by 180. Find the number?

200 190 210

Step-by-Step Logic:
1. Equation: x - (x / 10) = 180. 2. Multiply by 10: 10x - x = 1800. 3. 9x = 1800, so x = 200.

4. A number when divided by 4 is decreased by 45. Find the number?

50 60 70

Step-by-Step Logic:
1. Equation: x - (x / 4) = 45. 2. Multiply by 4: 4x - x = 180. 3. 3x = 180, so x = 60.

5. A number when divided by 2 is decreased by 25. Find the number?

40 50 60

Step-by-Step Logic:
1. Equation: x - (x / 2) = 25. 2. Multiply by 2: 2x - x = 50. 3. 1x = 50, so x = 50.
