Option 1 : 6 and 7, – and ×

1) 6 and 7, – and ×

45 + 24 ÷ 8 × 7 – 6 = 45 + 21 – 6 = 60

2) 8 and 6, ÷ and –

45 + 24 – 6 ÷ 8 × 7 = 45 + 24 – 5.25 = 45 + 18.75 = 63.75 ≠ 60

3) 7 and 8, + and –

45 – 24 ÷ 7 + 6 × 8 = 45 – 3.42 + 48 = 89.58 ≠ 60

4) 6 and 24, ÷ and +

45 ÷ 6 + 8 – 24 × 7 = 7.5 + 8 – 168 = – 152.5 ≠60

Hence, option 1 is the correct answer.
