Answer:
1 . The first chapter has 5 pages
2. the Sixth chapter has 20 pages
Step-by-step explanation:
Let the number of pages in the first story be x
As there are 3 more pages in the next story so second story will have x+3 pages
so, by this we can calculate the remaining 6 stories as well which will be
x+6 , x+9 , x+12 , x+15 , x+18 , and x+21
The total number of pages in the book are 124
so,
x+ x+3+ x+6 + x+9 + x+12 + x+15 + x+18 + x+21 =124
8x+84 = 124
8x =124 - 84
8x = 40
x = 5
therefore ,
no of pages in first story =x =5 pages
no of pages in sixth story = x+15 = 5 + 15 = 20 pages
