Correct Answer: B
Solution :
From the choices: [a] Inserting the sign (+, - \[\times \]) We get, 9 + 3 - 4\[\times \]6 = 29 [Use ?BODMAS? rule] 9 + 3 - 24 = 29 \[\Rightarrow \]12 ? 24 = 29 \[\Rightarrow \]- 12 \[\ne \] 29 [b] Inserting the sign (\[\times \],-,+) We get 9\[\times \]3 ? 4 + 6 = 29 [Use ?BODMAS? rule] 27 + 2 = 29 \[\Rightarrow \]29 = 29 [c] Inserting the sign (+,\[\times \],-) We get, 9 + 3\[\times \]4 ? 6 = 29 [Use ?BODMAS? rule] 9 + 12 ? 6 = 29 \[\Rightarrow \]15 \[\ne \]29 [d] Inserting the sign (\[\times \],+,-) We get, 9\[\times \]3 + 4 ? 6 = 29 [Use ?BODMAS? rule] 27 ? 2 = 29 \[\Rightarrow \]25\[\ne \]29
