Revenue share percentage increase

CMAT 2018 · Quantitative Techniques & Data Interpretation · Medium · Data Interpretation

The following pie chart provides information about the revenue share of six companies P, Q, R, S, T, U as a percentage of the total car market(in Rs.) in the year 2010. These are the only six companies producing car in the market.

Revenue shares in 2010: P = 22%, Q = 26%, R = 12%, S = 10%, T = 14%, U = 16%.

If the revenue share of company T increases by 20% in the year 2011, then find the percentage increase in the revenue share of these six companies in the year 2011 assuming that all the other companies except T generated the same revenue as they did in the year 2010.

  2. B.

    3.2%

  3. C.

    1.8%

  4. D.

    2.6%

Answer

A

Explanation

Assume total revenue in 2010 was 100. Revenue of T in 2010 = 14. Increase in revenue of T = 20%×14=2.820\% \times 14 = 2.8. Since all other companies' revenue remains unchanged, total revenue increase = 2.8. Percentage increase = 2.8100×100%=2.8%\frac{2.8}{100} \times 100\% = 2.8\%.
