Given equation, 27 + 11 × 9 - 36 ÷ 4 = 67
Option (1): 11 and 27
After the interchange, the new equation is-
⇒ 11 + 27 × 9 - 36 ÷ 4 = 67
⇒ 11 + 27 × 9 - 9 = 67
⇒ 254 - 9 = 67
⇒ 245 ≠ 67
Option (2): 4 and 9
Given equation, 27 + 11 × 9 - 36 ÷ 4 = 67
After the interchange, the new equation is-
27 + 11 × 4 - 36 ÷ 9 = 67
According to BODMAS rule,
27 + 11 × 4 - 4 = 67
27 + 44 - 4 = 6767 = 67
Option (3): 11 and 36
Given equation, 27 + 11 × 9 - 36 ÷ 4 = 67
After the interchange, the new equation is-
⇒ 27 + 36 × 9 - 11 ÷ 4 = 67
⇒ 27 + 36 × 9 - 2.75 = 67
⇒ 27 + 324 - 2.75 = 67
⇒ 351 - 2.75 = 67
⇒ 348.25 ≠ 67
Option (4): 27 and 36
Given equation, 27 + 11 × 9 - 36 ÷ 4 = 67
After the interchange, the new equation is-
⇒ 36 + 27 × 9 - 11 ÷ 4 = 67
⇒ 36 + 27 × 9 - 2.75 = 67
⇒ 36 + 243 - 2.75 = 67
⇒ 279 - 2.75 = 67
⇒ 276.25 ≠ 67
Hence, Option (2) is correct.
