None of these

Let's solve the given expression step by step and see which option matches:

- 150/25: This simplifies to 6 because 150 divided by 25 equals 6.

- v625: The square root of 625 is 25.

- 183/3: This division results in 61 because 183 divided by 3 equals 61.

- 1.2 × 50: Multiplying these gives 60.

Now, let's place these values back into the expression:

$$ 150/25 - v625 + 183/3 + 1.2 × 50 = 6 - 25 + 61 + 60 $$

- Adding and subtracting:

- 6 minus 25 is -19.

- Adding 61 gives 42.

- Adding 60 gives a total of 102.

Looking at the options:

- Option 1: 53

- Option 2: 48

- Option 3: 60

- Option 4: 56

- Option 5: None of these

Correct Answer: Option 5 - None of these.
