Statement 1 provides a dollar difference. When their pay levels are increased by 6% that dollar difference also increases by 6%. So Statement 1 points to an exact difference in their new pay levels.eitijan wrote:Jack and Mark both received hourly wage increases of 6 percent. After the increases, Jack's hourly wage was how many dollars per hour more than Mark's?
(1) Before the wage increases, Jack's hourly wage was $5.00 per hour more than Mark's.
(2) Before the wage increases, the ratio of Jack's hourly wage to Mark's hourly wage was 4 to 3.
Sufficient.
Statement 2 provides only the ratios of the amounts they were paid, and the question provides only a percent increase. So there isn't information that points to any exact dollar amount.
Examples:
Original - 400:300 After Increase - 424:318 Difference After Increase - 106
Original - 200:150 After Increase - 212:159 Difference After Increase - 53
Insufficient.
The correct answer is A.
