If the width of the path is 4 m and length of path is greater than its width by 4 m, what is the area of rectangular plot?
A) 412 m2
B) 426 m2
C) 395 m2
D) 352 m2
E) None of these
View Answer Option D
Solution:
See the figure
Path of 4 m wide is in the middle parallel to breadth, length of path which is breadth of rectangular plot is 4+4 = 8m
Path is in the middle, so BC = QS = x m
Now area of rest of the plot leaving the path is 112 this means area of ABCD + area of PQRS is
So x*8 + x*8 = 320
Solve, x = 20
So length of plot is 20+4+20 = 44, breadth is 8
So area = 44*8A dishonest shopkeeper - An article is marked at Rs 25,000. It was bought by the trader at successive discounts of 20% and 5%. After this he spent Rs 1,000 on its transportation and finally sold the article for Rs 25,000. What is his profit% in the whole transaction?
