Correct Answer: × and –
Solution : Given: 8 – 9 + 24 × 63 = 33
Let's check the given options – First option: × and – On interchanging the mathematical signs, we get – 8 × 9 + 24 – 63 = 33 L.H.S. = 8 × 9 + 24 – 63 = 72 + 24 – 63 = 96 – 63 = 33 = R.H.S. Second option: = and + On interchanging the mathematical signs, we get – 8 – 9 = 24 × 63 + 33 L.H.S. = 8 – 9 = –1 R.H.S. = 24 × 63 + 33 = 1512 + 33 = –1 ≠ 1545 Third option: – and = On interchanging the mathematical signs, we get – 8 = 9 + 24 × 63 – 33 R.H.S. = 9 + 24 × 63 – 33 = 9 + 1512 – 33 = 1521 – 33 = 1488 ≠ 8 Fourth option: – and + On interchanging the mathematical signs, we get – 8 + 9 – 24 × 63 = 33 L.H.S. = 8 + 9 – 24 × 63 = 8 + 9 – 1512 = 17 – 1512 = –1495 ≠ 33
So, only the first option satisfies the equation. Hence, the first option is correct.
