| 1) A book contains 119 pages. Each page has 22 lines. How many pages will the book contain if every page has 12 lines per page Answer: 218 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 22 x 119 = 12 x a a = (22 x 119)/ 12 = = 218 If there are 12 lines in one page, then the No of pages in the book = 218 |
| 2) A book contains 133 pages. Each page has 20 lines. How many pages will the book contain if every page has 14 lines per page Answer: 190 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 20 x 133 = 14 x a a = (20 x 133)/ 14 = = 190 If there are 14 lines in one page, then the No of pages in the book = 190 |
| 3) A book contains 146 pages. Each page has 20 lines. How many pages will the book contain if every page has 12 lines per page Answer: 243 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 20 x 146 = 12 x a a = (20 x 146)/ 12 = = 243 If there are 12 lines in one page, then the No of pages in the book = 243 |
| 4) A book contains 121 pages. Each page has 25 lines. How many pages will the book contain if every page has 16 lines per page Answer: 189 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 25 x 121 = 16 x a a = (25 x 121)/ 16 = = 189 If there are 16 lines in one page, then the No of pages in the book = 189 |
| 5) A book contains 144 pages. Each page has 22 lines. How many pages will the book contain if every page has 18 lines per page Answer: 176 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 22 x 144 = 18 x a a = (22 x 144)/ 18 = = 176 If there are 18 lines in one page, then the No of pages in the book = 176 |
| 6) A book contains 111 pages. Each page has 21 lines. How many pages will the book contain if every page has 15 lines per page Answer: 155 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 21 x 111 = 15 x a a = (21 x 111)/ 15 = = 155 If there are 15 lines in one page, then the No of pages in the book = 155 |
| 7) A book contains 102 pages. Each page has 21 lines. How many pages will the book contain if every page has 11 lines per page Answer: 195 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 21 x 102 = 11 x a a = (21 x 102)/ 11 = = 195 If there are 11 lines in one page, then the No of pages in the book = 195 |
| 8) A book contains 101 pages. Each page has 20 lines. How many pages will the book contain if every page has 12 lines per page Answer: 168 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 20 x 101 = 12 x a a = (20 x 101)/ 12 = = 168 If there are 12 lines in one page, then the No of pages in the book = 168 |
| 9) A book contains 119 pages. Each page has 21 lines. How many pages will the book contain if every page has 17 lines per page Answer: 147 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 21 x 119 = 17 x a a = (21 x 119)/ 17 = = 147 If there are 17 lines in one page, then the No of pages in the book = 147 |
| 10) A book contains 121 pages. Each page has 21 lines. How many pages will the book contain if every page has 13 lines per page Answer: 195 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 21 x 121 = 13 x a a = (21 x 121)/ 13 = = 195 If there are 13 lines in one page, then the No of pages in the book = 195 |
