A) \[8-\left( 5\times 3 \right)=25\]
B) \[\left( 3\times 5 \right)-8=34\]
C) \[(5-3)\times 8=26\]
D) \[(5-3)\times 8=12\]
Correct Answer: A
Solution :
From the choices. [a] Interchange - to \[\times \]or 5 to 8 We get, \[\mathbf{15}\text{ }\times \text{ }\left( \mathbf{8}\text{ }-\text{ }\mathbf{3} \right)\text{ }=\text{ }\mathbf{25}\] [Use 'BODMAS' rule] \[5\times 5=25\Rightarrow 25=25\] [b] Interchange - to\[\times \]or 5 to 8 We get, (3 - 8) - 5 = 34 [Use 'BODMAS' rule] 5 - 5 = 34 \[\Rightarrow \] - 10 \[\ne \]34 [c] Interchange - to \[\times \] or 5 to 8 We get, (8 \[\times \] 3) - 5 = 26 [Use 'BODMAS' rule] 24 - 5 - 26 \[\Rightarrow \] 19 \[\ne \] 26 [d] Interchange - to \[\times \] or 5 to 8 We get, (8 \[\times \] 3)- 5 = 12 [Use 'BODMAS' rule] 24 - 5 = 12 \[\Rightarrow \] 19 \[\ne \] 12
