Correct Answer: 46 – 6 + 4 × 5 ÷ 3 = 71
Solution : Given:
'+' stands for division
'×' stands for addition
'–' stands for multiplication
'÷' stands for subtraction
Option first: 46 ÷ 6 × 4 – 5 + 3 = 75.5
Now, replacing the symbols as per the code language given in the question, we get –
46 – 6 + 4 × 5 ÷ 3
Solving this equation using the BODMAS rule, we get –
= 46 – 6 + 4 × 1.67
= 46 – 6 + 6.67
= 46.67 is not equal to 75.5
Option second: 46 × 6 – 4 + 5 ÷ 3 = 70.1
Now, replacing the symbols as per the code language given in the question, we get –
46 + 6 × 4 ÷ 5 – 3
Solving this equation using the BODMAS rule, we get –
= 46 + 6 × 0.8 – 3
= 46 + 4.8 – 3
= 47.8 is not equal to 70.1
Option third: 46 – 6 + 4 × 5 ÷ 3 = 71
Now, replacing the symbols as per the code language given in the question, we get –
46 × 6 ÷ 4 + 5 – 3
Solving this equation using the BODMAS rule, we get –
= 46 × 1.5 + 5 – 3
= 69 + 5 – 3
= 71
Option fourth: 46 × 6 ÷ 4 – 5 + 3 = 74
Now, replacing the symbols as per the code language given in the question, we get –
46 + 6 – 4 × 5 ÷ 3
Solving this equation using the BODMAS rule, we get –
= 46 + 6 – 4 × 5 ÷ 3
= 46 + 6 – 6.67
= 45.33 is not equal to 74
Hence, option third is correct.
