The following graph shows the percentage change in the revenue of a company, during a period of 15 years, i.e., from the year 2005 to the year 2019.
In which of the following pairs of years, is the ratio of revenue the highest?
Let the revenue of the company in the year 2004 be Rs. 100x.
So, revenue of the company in the year 2005 will be = 100x + 100x × 25% = 125x
Similarly, we can find the revenue of the company for all the remaining years
By options:
Option A: Required ratio = 200x : 105x = 40 : 21 = 120 : 63
Option B: Required ratio = 250x : 126x = 125 : 63
Option C: Required ratio = 125x : 75x = 5 : 3
Option D: Required ratio = 100x : 60x = 5 : 3
Maximum ratio is for option B.
Hence, option B is correct.
