Correct Answer: 4 × 5 + 9 – 3 ÷ 4 = 15
Solution : Given: – stands for division, + stands for multiplication, ÷ stands for subtraction, and × stands for addition.
Let's check the options – First option: 4 × 5 + 9 – 3 ÷ 4 = 15 On interchanging the symbols, the equation becomes – 4 + 5 × 9 ÷ 3 – 4 = 15 Solving the L.H.S. of the equation – = 4 + 5 × 3 – 4 = 4 + 15 – 4 = 19 – 4 = 15 Second option: 4 – 5 × 9 + 3 ÷ 4 = 32 On interchanging the symbols, the equation becomes – 4 ÷ 5 + 9 × 3 – 4 = 32 Solving the L.H.S. of the equation – = 0.8 + 9 × 3 – 4 = 0.8 + 27 – 4 = 27.8 – 4 = 23.8 ≠ 32 Third option: 4 – 5 ÷ 18 × 3 – 4 = 70 On interchanging the symbols, the equation becomes – 4 ÷ 5 – 18 + 3 × 4 = 70 Solving the L.H.S. of the equation – = 0.8 – 18 + 3 × 4 = 0.8 – 18 + 12 = 12.8 – 18 = –5.2 ≠ 70 Fourth option: 4 ÷ 5 + 9 – 3 ÷ 4 = 81 On interchanging the symbols, the equation becomes – 4 – 5 × 9 ÷ 3 – 4 = 81 Solving the L.H.S. of the equation – = 4 – 5 × 3 – 4 = 4 – 15 – 4 = –15 ≠ 81
So, only the first option satisfies the given equation. Hence, the first option is correct.
