Detailed Solution
Download Solution PDFThe pattern followed here is:
Given: × and +, 7 and 4
I. 7 × 8 + 4 – 6 ÷ 3 = 57
Given: × and +, 7 and 4
⇒ 4 + 8 × 7 – 6 ÷ 3 = 57
⇒ 4 + 8 × 7 - 2 = 57
⇒ 4 + 56 - 2 = 57
⇒ 60 - 2 = 57
⇒ 58 ≠ 57 (Not Correct)
II. 4 × 8 – 9 ÷ 3 + 7 = 3
Given: × and +, 7 and 4
⇒ 7 + 8 – 9 ÷ 3 × 4 = 3
⇒ 7 + 8 - 3 × 4 = 3
⇒ 7 + 8 - 12 = 3
⇒ 15 - 12 = 3
⇒ 3 = 3 (Correct)
So, Only I is not correct.
Hence, the correct answer is "Option 2".
