Let the total book is 1 part

then, after 1st week remaining part = (1-7/13) = 6/13

after 2nd ----- =(6/13-6/13*5/9)=(6/13-10/39)=8/39

so basically 8/39=96

so 1 = 96*39/8

=12*39

=39(10+2)

=390+78=468.

then, after 1st week remaining part = (1-7/13) = 6/13

after 2nd ----- =(6/13-6/13*5/9)=(6/13-10/39)=8/39

so basically 8/39=96

so 1 = 96*39/8

=12*39

=39(10+2)

=390+78=468.

Let the total number of pages be x

Pages read in first week = 7x/13

remaining pages = x -7x/13 = 6x/13

5/9 of 6x/13 pages were read in second week. ie, 30x/117 pages.

remaining pages = 6x/13 - 30x/117 = 24x/117

24x/117 = 96

x/117 = 4

**x = 468**

Pages read in first week = 7x/13

remaining pages = x -7x/13 = 6x/13

5/9 of 6x/13 pages were read in second week. ie, 30x/117 pages.

remaining pages = 6x/13 - 30x/117 = 24x/117

24x/117 = 96

x/117 = 4

For a square ABCD, angle BAC + angle ACD is equal to

(1)45° (2)60°(3)90° (4)130°

(1)45° (2)60°(3)90° (4)130°

The option is 45 degree. in the square, each angle is 90 degree and required answer for diagonal. so it is 45 degree.

it is 90 degree only. BACis 45 degree and ACD is 45 degree. their sum is 90 degree.

BAC = 45° and ACD = 45°. So BAC+ACD = 90°

Actually the correct answer is 90 degree. Many people may be getting wrong just because of wrong diagram. correct the diagram and then see the correct answer u would get.

answer should be 180 as every angle of a square is 90 degree

so by adding two angles it should be ( 90+90)=180

so by adding two angles it should be ( 90+90)=180

AC is a diagonal and hence BAC can't be 90°
