Answer:
Correct Answer: A
Solution:
- $ 64.5% $ of $ 800+36.4% $ of $ 1500={{?}^{2}}+38 $
$ \Rightarrow $ $ \frac{64.5}{100}\times 800+\frac{36.4}{100}\times 1500={{?}^{2}}+38 $
$ \Rightarrow $ $ 516+546={{?}^{2}}+38 $
$ \Rightarrow $ $ {{?}^{2}}=1062-38 $
$ \Rightarrow $ $ {{?}^{2}}=1024 $
$ \Rightarrow $ $ ?=32 $
