Reemu read 1/5th pages of a book. If she reads further 40 pages, she would have read 7/10th pages of the book. How many pages are left to be read?

Solution:

Let us assume the total number of pages = x

Number of pages Reemu read = (1/5)x

Now let us examine the situation

(1/5)x + 40 = (7/10) x

= (7/10)x - (1/5)x = 40

=[(7 - 2)/10]x = 40

x = (40 × 10)/5 = 80

1/5 × 80 = 16

7/10 × 80 = 56

Total number of pages left to be read = 80 - 56 = 24
