### HideShow timer Statistics

The advanced technology of ski boots and bindings has brought a dramatic drop in the incidence of injuries that occur on the slopes of ski resorts: from 9 injuries per 1,000 skiers in 1950 to 3 in 1980. As a result, the remainder of ski-related injuries, which includes all injuries occurring on the premises of a ski resort but not on the slopes, rose from 10 percent of all ski-related injuries in 1950 to 25 percent in 1980. The incidence of these injuries, including accidents such as falling down steps, increases with the amount of alcohol consumed per skier.

Which one of the following can be properly inferred from the passage?
(A) As the number of ski injuries that occur on the slopes decreases, the number of injuries that occur on the premises of ski resorts increases.
(B) The amount of alcohol consumed per skier increased between 1950 and 1980.
(C) The technology of ski boots and bindings affects the incidence of each type of ski-related injury.
(D) If the technology of ski boots and bindings continues to advance, the incidence of ski-related injuries will continue to decline.
(E) Injuries that occurred on the slopes of ski resorts made up a smaller percentage of ski-related injuries in 1980 than in 1950.

Which one of the following can be properly inferred from the passage?
(A) As the number of ski injuries that occur on the slopes decreases, the number of injuries that occur on the premises of ski resorts increases.(wrong-there is no relation between two types of injuries)
(B) The amount of alcohol consumed per skier increased between 1950 and 1980(wrong-no proof to conclude this).
(C) The technology of ski boots and bindings affects the incidence of each type of ski-related injury.(wrong-the second type of injury is not shown any relation to technology)
(D) If the technology of ski boots and bindings continues to advance, the incidence of ski-related injuries will continue to decline.(wrong-no proof given to show that the trend will continue in future)
(E) Injuries that occurred on the slopes of ski resorts made up a smaller percentage of ski-related injuries in 1980 than in 1950.(correct-in 1980 it was 75% whereras in 1950 it was 90%.)

I heard percentage problems are some of the harder ones that GMAT will throw at you.

Situation: improving tech of boots & bindings made skiing safer, thus causing a much smaller number of ski-related injuries. At the same time, we know that other types of injuries (ones not related to boots, bindings, etc) increased as a proportion of all ski-related injuries.

We have no idea about the actual quantities of injuries that occurred (except that "on the slope" injuries decreased), since we're only given percentages & ratios.

Therefore, all else being equal, the only thing we can reasonably infer is that skiing on the slopes caused a smaller portion of ski-related injuries; (E) articulates this inference perfectly.

A) Not necessarily. There is nothing in the argument that relates the two.
B) Nope. Although there is a correlation, and the % of resort accidents increased, it doesn’t necessarily mean people are drinking more alcohol. It may be the case that since less accidents are happening on the slopes, naturally, the % of injuries happening on the resort is increasing and alcohol consumption is staying the same.
C) EACH type? No. It helps with slope-related injuries, but it doesn’t help with resort-related injuries.
D) Injuries have declined due to better technology in the past, but there is no indication that this will continue in the future.
E) This is correct b/c in 1980, 25% of injuries were resort-related, which means 75% were slope-related. In 1950, 10% were resort-related, which means 90% were slope-related. We know that all injuries are either slope-related or not slope-related b/c of the phrase “the remainder of ski-related injuries.”

I thought this was tricky.
