A $8 \times 3 + 63 \div 9 - 6 = 25$
B $42 \div 6 + (2 \times 5) \times 1 + 9 = 26$
C $13 - 7 + 8 \times 9 + 63 \div 7 = 86$
D $9 \times 4 + (12 + 2) - 30 \div 3 = 40$

Solution & Step-by-step Explanation

Let's check each option using BODMAS rules:Option A: 8 \times 3 + 63 \div 9 - 6 = 24 + 7 - 6 = 25 (Correct)Option B: 42 \div 6 + (10) \times 1 + 9 = 7 + 10 + 9 = 26 (Correct)Option C: 13 - 7 + 8 \times 9 + 63 \div 7 = 13 - 7 + 72 + 9 = 6 + 72 + 9 = 87 .The equation gives 86, so option C is INCORRECT.Option D: 9 \times 4 + 14 - 30 \div 3 = 36 + 14 - 10 = 40 (Correct)
