Answer 1

The correct option is C 110.25, 128.55

The current trend can be analysed by observing the revenue of previous 2 sets
So the trend of revenue growth of Company A $=\frac{105-100}{100}\times 100=5\%$
So revenue of company A in 2013 is $105\times 1.05=110.25$
So the trend of revenue growth of Company B $=\frac{75-70}{70}\times 100$ = 7.14%
So revenue of company A in 2013 is $75\times 1.714=128.55$
