Option A
is the correct answer.
Explanatory Answer
Let us try to calculate possible amounts of money raised by firms Alfloo and Elavalaki.
Firm Alfloo:
This is the least possible money raised if in 2010 money raised increased by 2 crores. Here, the total sum is 23.
So this case is not possible. Therefore, in 2010 money raised must increase by 1 crore.
(Note: Again if money raised in 2011 is ‘4’ then least possible sum is 22 for combination 1-2-4-5-4-3-2-1)
Firm Elavalaki:
Hence, the money raised in year 2015 can be: 2 + 1 + 3 + 1 + 1 or 0 = 7 or 8 crores.
