Data related to number of projects handled by two companies
(A and B) during 5 years)
Question 158
If the number of projects handled by company A increased by 20% from 2007 to 2008 and by 5% from 2008 to 2009, what was the number of projects handled by company A in 2009?
Solution
Number of projects handled by company A in 2007 = 190
=> Number of projects handled by company A in 2008 = $$190 + \frac{20}{100} \times 190$$
= $$190 + 38 = 228$$
$$\therefore$$ Number of projects handled by company A in 2009 = $$228 + \frac{5}{100} \times 228$$
= $$228 + 11.4 = 239.4$$
