Solution

The correct option is B 2012 and 2019

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.
