Answers
Answer:
Given : a boy reads 1/4 of a book on the first day.
on the second day he reads 1/3 of the remaining portion.
100 pages are left to be read
To Find what portion of the book does the boy read in the two days? find how many pages are there in the book?
Step-by-step explanation:
Solution:
Let say total Pages in Book = 4B
boy reads 1/4 of a book on the first day
=> Read on 1st day = (1/4)4B = B
Remaining Pages = 4B - B = 3B
second day he reads 1/3 of the remaining portion.
=> Read on 2nd Day = (1/3)3B = B
Remaining Pages = 3B - B = 2B
Boys read in two days = 2B/4B = 1/2
Half Portion
2B = 100
=> B = 50
=> 4B = 200
There are 200 Pages in Book
