Question

raju read 10 pages of a book in one day and the next day he read one third of the remaining pages then 24 pages left to read ?

Answer 1

let x pages in the book
first day he reads 10 pages
it means pages remaining=x-10

next day he reads (x-10)/3
now pages left =(x-10)-(x-10)/3=2(x-10)/3
which is equal to 24
hence,
2(x-10)/3=24

2(x-10)=72

(x-10)=36

x=46

hence 46 pages available in the book

Answer 2

Let the total number of pages in the book be x ;
Raju reads 10 pages in one day
------------------------------------------
Now,
Pages left = (x-10)
------------------------------------------
Pages read by raju on next day = (x-10)/3
==========================
Now,
Pages left = (x-10) - (x-10)/3
24 = x-10 -(x/3) + (10/3)
24+10 -(10/3) = x-(x/3)
(102-10)/3 = (3x-x)/3
92 = 2x
x = 46

Hence the Total number of pages the book has = 46.
