| 1) A book contains 149 pages. Each page has 20 lines. How many pages will the book contain if every page has 15 lines per page Answer: 199 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 149 = 15 x a a = (20 x 149)/ 15 = = 199 If there are 15 lines in one page, then the No of pages in the book = 199 |
| 2) A book contains 118 pages. Each page has 22 lines. How many pages will the book contain if every page has 16 lines per page Answer: 162 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 118 = 16 x a a = (22 x 118)/ 16 = = 162 If there are 16 lines in one page, then the No of pages in the book = 162 |
| 3) A book contains 104 pages. Each page has 21 lines. How many pages will the book contain if every page has 17 lines per page Answer: 128 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 104 = 17 x a a = (21 x 104)/ 17 = = 128 If there are 17 lines in one page, then the No of pages in the book = 128 |
| 4) A book contains 113 pages. Each page has 21 lines. How many pages will the book contain if every page has 18 lines per page Answer: 132 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 113 = 18 x a a = (21 x 113)/ 18 = = 132 If there are 18 lines in one page, then the No of pages in the book = 132 |
| 5) A book contains 129 pages. Each page has 21 lines. How many pages will the book contain if every page has 13 lines per page Answer: 208 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 129 = 13 x a a = (21 x 129)/ 13 = = 208 If there are 13 lines in one page, then the No of pages in the book = 208 |
| 6) A book contains 118 pages. Each page has 20 lines. How many pages will the book contain if every page has 16 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 20 x 118 = 16 x a a = (20 x 118)/ 16 = = 148 If there are 16 lines in one page, then the No of pages in the book = 148 |
| 7) A book contains 136 pages. Each page has 22 lines. How many pages will the book contain if every page has 11 lines per page Answer: 272 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 136 = 11 x a a = (22 x 136)/ 11 = = 272 If there are 11 lines in one page, then the No of pages in the book = 272 |
| 8) A book contains 107 pages. Each page has 22 lines. How many pages will the book contain if every page has 10 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 22 x 107 = 10 x a a = (22 x 107)/ 10 = = 235 If there are 10 lines in one page, then the No of pages in the book = 235 |
| 9) A book contains 114 pages. Each page has 24 lines. How many pages will the book contain if every page has 15 lines per page Answer: 182 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 114 = 15 x a a = (24 x 114)/ 15 = = 182 If there are 15 lines in one page, then the No of pages in the book = 182 |
| 10) A book contains 119 pages. Each page has 22 lines. How many pages will the book contain if every page has 13 lines per page Answer: 201 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 = 13 x a a = (22 x 119)/ 13 = = 201 If there are 13 lines in one page, then the No of pages in the book = 201 |
