Answer 2

Answer:

I CAN'T FIND THE ANSWER . SEE THE EXAMPLE

Explanation:

From the question it is given that,

Reemu read (1/5)th pages of a book.

Let us assume the total number of pages in the book be 'P'.

Then, number of pages read by Reemu =(1/5) of P = (1/5) * P

And also it is given the question, If she reads further 40 pages, she would have read (7/10)th pages of the book.

=(7/10)* P So,((1/5)* P)+40=(7/10)* P(P+ 200)/5=(7P/10)

By cross mutliplication we get,

2P + 400 = 7P

5P = 400

P=400/5... [divide both numerator and denominator by 5]

P = 80

Then, pages read by Reema = T pages. Pages read P - (7P / 10) = (3P / 10)(3/10) * 8024 pages

Therefore, 24 pages are left to be read.
