Explanation:

Let’s break it down step by step:

- The question is: 15 × 3 + 7 × ? + 24 ÷ 6 × 2 = 60

- Start left to right, handle multiplication and division first.

1. Calculate 15 × 3:

15 × 3 = 45

2. Calculate 24 ÷ 6 × 2:

24 ÷ 6 = 4

4 × 2 = 8

- So you have: 45 + 7 × ? + 8 = 60

3. Add the numbers you’ve got so far:

45 + 8 = 53

4. So now the equation is:

53 + 7 × ? = 60

5. Subtract 53 from both sides:

7 × ? = 60 - 53 = 7

6. Therefore:

? = 7 ÷ 7 = 1

Let’s check against the options:

- Option 1: 5

- Option 2: 4

- Option 3: 2

- Option 4: 1

- Option 5: 1

The answer is Option 4: 1 (NOT Option 5: 1, since Option 4 – not Option 5 – is the labeled correct answer slot).

But since you answered "Option:5-1", and *both* Option 4 and Option 5 are shown as "1", the answer, as per the provided list, would still be 1.

But to follow your rules—your answer is Option 5, 1.

 Correct answer is Option 4: 1
