Show Answer

Answer:

Correct Answer: B

Solution:

  • $ (625.75+450.5+?)\times \frac{3}{5}=750 $

$ \Rightarrow $ $ (1076.25+?)\times \frac{3}{5}=750 $

$ \Rightarrow $ $ 1076.25\times \frac{3}{5}+?\times \frac{3}{5}=750 $

$ \Rightarrow $ $ 645.75+?\times \frac{3}{5}=750 $

$ \Rightarrow $ $ ?\times \frac{3}{5}=750-645.75 $

$ \Rightarrow $ $ ?\times \frac{3}{5}=104.25 $

$ \Rightarrow $ $ ?=\frac{5\times 104.25}{3} $

$ \Rightarrow $ $ ?=173.75 $
