| 1) A book contains 131 pages. Each page has 21 lines. How many pages will the book contain if every page has 15 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 21 x 131 = 15 x a a = (21 x 131)/ 15 = = 183 If there are 15 lines in one page, then the No of pages in the book = 183 |
| 2) A book contains 139 pages. Each page has 20 lines. How many pages will the book contain if every page has 11 lines per page Answer: 253 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 139 = 11 x a a = (20 x 139)/ 11 = = 253 If there are 11 lines in one page, then the No of pages in the book = 253 |
| 3) A book contains 121 pages. Each page has 24 lines. How many pages will the book contain if every page has 17 lines per page Answer: 171 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 121 = 17 x a a = (24 x 121)/ 17 = = 171 If there are 17 lines in one page, then the No of pages in the book = 171 |
| 4) A book contains 135 pages. Each page has 21 lines. How many pages will the book contain if every page has 14 lines per page Answer: 203 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 135 = 14 x a a = (21 x 135)/ 14 = = 203 If there are 14 lines in one page, then the No of pages in the book = 203 |
| 5) A book contains 133 pages. Each page has 21 lines. How many pages will the book contain if every page has 17 lines per page Answer: 164 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 133 = 17 x a a = (21 x 133)/ 17 = = 164 If there are 17 lines in one page, then the No of pages in the book = 164 |
| 6) A book contains 149 pages. Each page has 22 lines. How many pages will the book contain if every page has 18 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 22 x 149 = 18 x a a = (22 x 149)/ 18 = = 182 If there are 18 lines in one page, then the No of pages in the book = 182 |
| 7) A book contains 121 pages. Each page has 25 lines. How many pages will the book contain if every page has 18 lines per page Answer: 168 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 121 = 18 x a a = (25 x 121)/ 18 = = 168 If there are 18 lines in one page, then the No of pages in the book = 168 |
| 8) A book contains 141 pages. Each page has 24 lines. How many pages will the book contain if every page has 11 lines per page Answer: 308 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 141 = 11 x a a = (24 x 141)/ 11 = = 308 If there are 11 lines in one page, then the No of pages in the book = 308 |
| 9) A book contains 101 pages. Each page has 21 lines. How many pages will the book contain if every page has 13 lines per page Answer: 163 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 = 13 x a a = (21 x 101)/ 13 = = 163 If there are 13 lines in one page, then the No of pages in the book = 163 |
| 10) A book contains 124 pages. Each page has 23 lines. How many pages will the book contain if every page has 16 lines per page Answer: 178 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 124 = 16 x a a = (23 x 124)/ 16 = = 178 If there are 16 lines in one page, then the No of pages in the book = 178 |
