Answer:

Correct Answer: D

Solution:

  • 105.27% of 1200.11 + 11.80% of 2360.85 = 21.99% of ? + 1420.99

$ \Rightarrow $ 105% of 1200 + 12% of 2360 = 22% of ? + 1421

$ \Rightarrow $ $ 1260+283.2=0.22\times ?+1421 $

$ \Rightarrow $ $ 0.22\times ?=122.2 $

$ \Rightarrow $ $ ?=\frac{122.2}{0.22}=555.45\approx 550 $
