Explanation:

- Let's first find the original number.

- 25% of a number is given as 6.

- This means 0.25 times the number equals 6.

- To find the number, divide 6 by 0.25, which results in 24.

- Now, find the number which is 50% more than the initial number:

- 50% more than a number means adding half of that number to itself.

- 50% of 24 is 12, so adding this to the original number (24 + 12) gives us 36.

- Compare with the options provided:

- Option 1: 36

- Option 2: 24

- Option 3: 30

- Option 4: 18
