Answer:
Amaya is wrong.
Step-by-step explanation:
The perimeter of the square is 20 inches, which means each side of the square needs to add up to 20 inches. If the side length of that side Amaya pointed out is 4 inches, then the total perimeter would only be 18 inches, in another case, if they were talking about the area of the square/rectangle (now), it would be 20 inches. So, Amaya is wrong.
Yes your answer is solved correctly
Answer:
(i) number of student passed in math is 60
(ii) number of student passed in science is 70
only math is 10
and only science is 20
Suppose the original price to be x.
62%x=296.4
Divide both sides by 62% to get x=478, which is the original price.
