The pie chart shows the revenue share of six companies P, Q, R, S, T and U as a percentage of the total revenue (in ₹) of the car market in 2010. These are the only six companies producing cars in the market.
Revenue share, 2010
P22%Q26%R12%S10%T14%U16%
If the revenue of company T increases by 20% in 2011 and every other company earns the same revenue as in 2010, by what percentage does the total revenue of the six companies increase in 2011?
Answer and explanation
Correct answer A
The total revenue rises by 2.8%. Take the 2010 total as 100; T's revenue is 14. A 20% rise adds to T and nothing to the others, so the total becomes 102.8, an increase of 2.8%. A figure of 3.2% would follow from applying the rise to U's 16% share instead of T's, and 1.8% and 2.6% do not equal 20% of 14.
