| 1) A book contains 125 pages. Each page has 24 lines. How many pages will the book contain if every page has 13 lines per page Answer: 231 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 125 = 13 x a a = (24 x 125)/ 13 = = 231 If there are 13 lines in one page, then the No of pages in the book = 231 |
| 2) A book contains 125 pages. Each page has 20 lines. How many pages will the book contain if every page has 14 lines per page Answer: 179 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 125 = 14 x a a = (20 x 125)/ 14 = = 179 If there are 14 lines in one page, then the No of pages in the book = 179 |
| 3) A book contains 128 pages. Each page has 25 lines. How many pages will the book contain if every page has 11 lines per page Answer: 291 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 128 = 11 x a a = (25 x 128)/ 11 = = 291 If there are 11 lines in one page, then the No of pages in the book = 291 |
| 4) A book contains 150 pages. Each page has 21 lines. How many pages will the book contain if every page has 12 lines per page Answer: 263 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 150 = 12 x a a = (21 x 150)/ 12 = = 263 If there are 12 lines in one page, then the No of pages in the book = 263 |
| 5) A book contains 131 pages. Each page has 21 lines. How many pages will the book contain if every page has 11 lines per page Answer: 250 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 131 = 11 x a a = (21 x 131)/ 11 = = 250 If there are 11 lines in one page, then the No of pages in the book = 250 |
| 6) A book contains 114 pages. Each page has 24 lines. How many pages will the book contain if every page has 14 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 24 x 114 = 14 x a a = (24 x 114)/ 14 = = 195 If there are 14 lines in one page, then the No of pages in the book = 195 |
| 7) A book contains 135 pages. Each page has 22 lines. How many pages will the book contain if every page has 10 lines per page Answer: 297 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 135 = 10 x a a = (22 x 135)/ 10 = = 297 If there are 10 lines in one page, then the No of pages in the book = 297 |
| 8) A book contains 103 pages. Each page has 22 lines. How many pages will the book contain if every page has 11 lines per page Answer: 206 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 103 = 11 x a a = (22 x 103)/ 11 = = 206 If there are 11 lines in one page, then the No of pages in the book = 206 |
| 9) A book contains 138 pages. Each page has 25 lines. How many pages will the book contain if every page has 14 lines per page Answer: 246 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 138 = 14 x a a = (25 x 138)/ 14 = = 246 If there are 14 lines in one page, then the No of pages in the book = 246 |
| 10) A book contains 101 pages. Each page has 21 lines. How many pages will the book contain if every page has 14 lines per page Answer: 152 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 101 = 14 x a a = (21 x 101)/ 14 = = 152 If there are 14 lines in one page, then the No of pages in the book = 152 |
