| 1) A book contains 146 pages. Each page has 21 lines. How many pages will the book contain if every page has 13 lines per page Answer: 236 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 = 13 x a a = (21 x 146)/ 13 = = 236 If there are 13 lines in one page, then the No of pages in the book = 236 |
| 2) A book contains 120 pages. Each page has 25 lines. How many pages will the book contain if every page has 16 lines per page Answer: 188 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 120 = 16 x a a = (25 x 120)/ 16 = = 188 If there are 16 lines in one page, then the No of pages in the book = 188 |
| 3) A book contains 103 pages. Each page has 25 lines. How many pages will the book contain if every page has 15 lines per page Answer: 172 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 103 = 15 x a a = (25 x 103)/ 15 = = 172 If there are 15 lines in one page, then the No of pages in the book = 172 |
| 4) A book contains 108 pages. Each page has 22 lines. How many pages will the book contain if every page has 17 lines per page Answer: 140 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 108 = 17 x a a = (22 x 108)/ 17 = = 140 If there are 17 lines in one page, then the No of pages in the book = 140 |
| 5) A book contains 131 pages. Each page has 25 lines. How many pages will the book contain if every page has 15 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 25 x 131 = 15 x a a = (25 x 131)/ 15 = = 218 If there are 15 lines in one page, then the No of pages in the book = 218 |
| 6) A book contains 132 pages. Each page has 21 lines. How many pages will the book contain if every page has 18 lines per page Answer: 154 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 132 = 18 x a a = (21 x 132)/ 18 = = 154 If there are 18 lines in one page, then the No of pages in the book = 154 |
| 7) A book contains 129 pages. Each page has 20 lines. How many pages will the book contain if every page has 11 lines per page Answer: 235 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 129 = 11 x a a = (20 x 129)/ 11 = = 235 If there are 11 lines in one page, then the No of pages in the book = 235 |
| 8) A book contains 126 pages. Each page has 24 lines. How many pages will the book contain if every page has 14 lines per page Answer: 216 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 126 = 14 x a a = (24 x 126)/ 14 = = 216 If there are 14 lines in one page, then the No of pages in the book = 216 |
| 9) A book contains 124 pages. Each page has 24 lines. How many pages will the book contain if every page has 14 lines per page Answer: 213 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 124 = 14 x a a = (24 x 124)/ 14 = = 213 If there are 14 lines in one page, then the No of pages in the book = 213 |
| 10) A book contains 125 pages. Each page has 23 lines. How many pages will the book contain if every page has 12 lines per page Answer: 240 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 125 = 12 x a a = (23 x 125)/ 12 = = 240 If there are 12 lines in one page, then the No of pages in the book = 240 |
