Correct Answer: 18 + 6 – 4 × 2 ÷ 3 = 26
Solution : Given:
'+' means '×'
'–' means '÷'
'×' means '+'
'÷' means '–'
Option first: 18 – 6 × 7 ÷ 2 + 8 = 63
Now, replacing the symbols as per the code language given in the question, we get –
18 – 6 × 7 ÷ 2 + 8
Solving this equation using the BODMAS rule, we get –
= 18 – 6 × 3.5 + 8
= 18 – 21 + 8
= 5 is not equal to 63
Option second: 18 ÷ 6 + 4 – 2 ÷ 3 = 22
18 – 6 × 4 ÷ 2 – 3
= 18 – 6 × 2 – 3
= 18 – 12 – 3
= 3 is not equal to 22
Option third: 18 + 6 – 4 × 2 ÷ 3 = 26
18 × 6 ÷ 4 + 2 – 3
= 18 × 1.5 + 2 – 3
= 27 + 2 – 3
= 26
Option fourth: 18 × 6 – 4 + 7 × 8 = 47
18 + 6 ÷ 4 × 7 + 8
= 18 + 1.5 × 7 + 8
= 18 + 10.5 + 8
= 36.5 is not equal to 47
Hence, option third is correct.
