25. The perimeter of the total apartment is 2 ( 22 + 19 )

    = 2 ´ 41 = 82 feet.

    Hence D.

    Questions 26 - 29 refer to the diagram.

    

     

26. Using Ven diagram in which the total ( 100% ) is represented by the rectangle and the two circles representing cold drinks and snacks, the intersection of which will represent the unknown percentage ( x% ) of students having both cold drinks and snacks. We therefore have ( 80 - x ) + ( x ) + ( 60 - x ) + ( 5 ) = 100.

    \ x = 45%

    Hence B.

27. Those who ordered drinks but not snacks ( i.e. drinks only ) is 80 - x or 80 - 45 = 35%

    Hence C.

28. Snacks only percentage is ( 60 - x ) i.e. 60 - 45 = 15%. Hence the number of students who ordered snacks only is 15% of the total of 480

    

    Hence A.
