Is it A?

If the term " constant amount" implies that the profit increases every year in an A.P. , then it is A.

A is the answer

Statement 1
Let x be the annual profit increased, a constant amount
212000 + 4x = 242000
=> x = 7500
For year 1991 we can compute the answer based on x = 7500 and knowing the profit for the previous years

Statement 2 is useless
