We require either income for one of the year or difference of the income between both the year as we have percentage increase to find the rest of the information.

1) Details of 1st half of the year and 2nd half of the year is provided using this we can find income of the entire year and then can find the rest hence, Satisfied

2) Difference between both the years income provided hence using this we can find rest using this hence, Satisfied

Total income for 1990 can be calculated by adding both, now we have income in 1990 we can calculate income of 1991 Sufficient

(2) Ms. Smith's income for 1991 was $7,500 greater than her income for 1990.
we know that salary is 20% more than it was in 1990 and value of 20% is ie 7500 is given in second statement. Sufficient
