  • A. 40 and 16
  • B. 8 and 12
  • C. 6 and 12
  • D. 14 and 16
Correct Answer: Option B - (40×6) ÷ 8 + 14 – (7 × 16) + (13 ×12) = 26 from option (b), On interchanging 8 and 12. (40 × 6) ÷ 12 + 14 – (7 × 16) + (13 × 8) = 240 ÷ 12 + 14 – 112 + 104 = 20 + 14 – 8 = 20 + 6 = 26
B. (40×6) ÷ 8 + 14 – (7 × 16) + (13 ×12) = 26 from option (b), On interchanging 8 and 12. (40 × 6) ÷ 12 + 14 – (7 × 16) + (13 × 8) = 240 ÷ 12 + 14 – 112 + 104 = 20 + 14 – 8 = 20 + 6 = 26

Explanations:

(40×6) ÷ 8 + 14 – (7 × 16) + (13 ×12) = 26 from option (b), On interchanging 8 and 12. (40 × 6) ÷ 12 + 14 – (7 × 16) + (13 × 8) = 240 ÷ 12 + 14 – 112 + 104 = 20 + 14 – 8 = 20 + 6 = 26
