Number of projects handled by company A in 2008 = 180

=> Number of projects handled by company A in 2009 = $$180 + \frac{25}{100} \times 180$$

= $$225$$

Number of projects handled by company E in 2008 = 240

=> Number of projects handled by company E in 2009 = $$240 - \frac{35}{100} \times 240$$

= $$156$$

$$\therefore$$ Total number of projects handled by companies A and E together in 2009 = 225 + 156 = 381
