| 1) A book contains 119 pages. Each page has 25 lines. How many pages will the book contain if every page has 10 lines per page Answer: 298 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 119 = 10 x a a = (25 x 119)/ 10 = = 298 If there are 10 lines in one page, then the No of pages in the book = 298 |
| 2) A book contains 133 pages. Each page has 23 lines. How many pages will the book contain if every page has 10 lines per page Answer: 306 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 133 = 10 x a a = (23 x 133)/ 10 = = 306 If there are 10 lines in one page, then the No of pages in the book = 306 |
| 3) A book contains 113 pages. Each page has 20 lines. How many pages will the book contain if every page has 15 lines per page Answer: 151 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 113 = 15 x a a = (20 x 113)/ 15 = = 151 If there are 15 lines in one page, then the No of pages in the book = 151 |
| 4) A book contains 143 pages. Each page has 22 lines. How many pages will the book contain if every page has 14 lines per page Answer: 225 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 143 = 14 x a a = (22 x 143)/ 14 = = 225 If there are 14 lines in one page, then the No of pages in the book = 225 |
| 5) A book contains 136 pages. Each page has 25 lines. How many pages will the book contain if every page has 18 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 136 = 18 x a a = (25 x 136)/ 18 = = 189 If there are 18 lines in one page, then the No of pages in the book = 189 |
| 6) A book contains 105 pages. Each page has 21 lines. How many pages will the book contain if every page has 11 lines per page Answer: 200 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 105 = 11 x a a = (21 x 105)/ 11 = = 200 If there are 11 lines in one page, then the No of pages in the book = 200 |
| 7) A book contains 132 pages. Each page has 24 lines. How many pages will the book contain if every page has 16 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 132 = 16 x a a = (24 x 132)/ 16 = = 198 If there are 16 lines in one page, then the No of pages in the book = 198 |
| 8) A book contains 104 pages. Each page has 23 lines. How many pages will the book contain if every page has 11 lines per page Answer: 217 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 104 = 11 x a a = (23 x 104)/ 11 = = 217 If there are 11 lines in one page, then the No of pages in the book = 217 |
| 9) A book contains 142 pages. Each page has 24 lines. How many pages will the book contain if every page has 13 lines per page Answer: 262 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 142 = 13 x a a = (24 x 142)/ 13 = = 262 If there are 13 lines in one page, then the No of pages in the book = 262 |
| 10) A book contains 124 pages. Each page has 20 lines. How many pages will the book contain if every page has 11 lines per page Answer: 225 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 124 = 11 x a a = (20 x 124)/ 11 = = 225 If there are 11 lines in one page, then the No of pages in the book = 225 |
