One day, during their vacation at a beach resort, Shelia found twice as many sea shells as Anita and Anita found `5` shells more than sandy. Together sandy and Sheila found `16` sea shells. How many did each of them find?

Text Solution

Verified by Experts

The correct Answer is:
The number of sea shells found by Shelia `= 2 (x + 5) = 2 (4 + 5) = 2(9) = 18`
The number of sea shells found by Shelia `= 2 (x + 5) = 2 (4 + 5) = 2(9) = 18`

The shells of crabs found around a particular coastal location in Japan seem mostly to resemble the legendary face of a Samurai. Given below are two explanations of this observed fact. Which of these strikes you as a scientific explanation ? (a) A tragic sea accident several centuries ago drowned a young Samurai. As a tribute to his bravery, nature through its inscrutable ways immortalized his face by imprinting it on the crab shells in that area. (b) After the sea tragedy, fishermen in that area, in a gesture of honour to their dead hero, let free any crab shell caught by them which accidentally had a shape resembling the face of a Samurai. Consequently, the particular shape of the crab shell survived longer and therefore in course of time the shape was genetically propagated. This is an example of evolution by artificial selection. [Note : This interesting illustration taken from Carl Sagan's ''The Cosmos' highlights the fact that often strange and inexplicable facts which on the first sight appear 'supernatural' actually turn out to have simple scientific explanations. Try to think out other examples of this kind].
