Answer 1

ANSWER

The answer is option B

Evaluating LHS of each equation by substituting the actual symbols and using the BODMAS rule and comparing it with the RHS we get,

Option A

  LHS =18+6−7+5×2

 =18÷6+7÷5−2=3+1.4−2=4.4−2=2.4=20=RHS

Option B

  LHS =18+6÷7×5−2

 =18÷6×7−5+2=3×7−5+2=21−5+2=18=RHS

Option C

  LHS =18×6÷7+5−2

 =18−6×7÷5+2=18−6×1.4+1.4+2=18−10.4=8.4=16=RHS

Option D

  LHS =18÷6×7+6−2

 =18×6−7÷6+2=108−7÷6+2=108−1.16+2=108−3.16=94.84=22=RH
