| 1) A book contains 119 pages. Each page has 23 lines. How many pages will the book contain if every page has 13 lines per page Answer: 211 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 23 x 119 = 13 x a a = (23 x 119)/ 13 = = 211 If there are 13 lines in one page, then the No of pages in the book = 211 |
| 2) A book contains 106 pages. Each page has 20 lines. How many pages will the book contain if every page has 11 lines per page Answer: 193 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 106 = 11 x a a = (20 x 106)/ 11 = = 193 If there are 11 lines in one page, then the No of pages in the book = 193 |
| 3) A book contains 106 pages. Each page has 21 lines. How many pages will the book contain if every page has 15 lines per page Answer: 148 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 106 = 15 x a a = (21 x 106)/ 15 = = 148 If there are 15 lines in one page, then the No of pages in the book = 148 |
| 4) A book contains 135 pages. Each page has 20 lines. How many pages will the book contain if every page has 15 lines per page Answer: 180 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 135 = 15 x a a = (20 x 135)/ 15 = = 180 If there are 15 lines in one page, then the No of pages in the book = 180 |
| 5) A book contains 140 pages. Each page has 24 lines. How many pages will the book contain if every page has 17 lines per page Answer: 198 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 24 x 140 = 17 x a a = (24 x 140)/ 17 = = 198 If there are 17 lines in one page, then the No of pages in the book = 198 |
| 6) A book contains 146 pages. Each page has 21 lines. How many pages will the book contain if every page has 15 lines per page Answer: 204 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 146 = 15 x a a = (21 x 146)/ 15 = = 204 If there are 15 lines in one page, then the No of pages in the book = 204 |
| 7) A book contains 113 pages. Each page has 25 lines. How many pages will the book contain if every page has 16 lines per page Answer: 177 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 113 = 16 x a a = (25 x 113)/ 16 = = 177 If there are 16 lines in one page, then the No of pages in the book = 177 |
| 8) A book contains 117 pages. Each page has 25 lines. How many pages will the book contain if every page has 16 lines per page Answer: 183 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 117 = 16 x a a = (25 x 117)/ 16 = = 183 If there are 16 lines in one page, then the No of pages in the book = 183 |
| 9) A book contains 131 pages. Each page has 23 lines. How many pages will the book contain if every page has 11 lines per page Answer: 274 pages SOLUTION 1 : Given :
As the No of lines per page decreases, No of pages increases . It is in inverses variation So, xy = Constant 23 x 131 = 11 x a a = (23 x 131)/ 11 = = 274 If there are 11 lines in one page, then the No of pages in the book = 274 |
| 10) A book contains 131 pages. Each page has 23 lines. How many pages will the book contain if every page has 16 lines per page Answer: 188 pages SOLUTION 1 : Given :
