Answer 1

Answer:

56 pages are left to read

Step-by-step explanation:

Let total pages be x

from question we know that

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

40 =7x/10 - x/5

Lcm

40 = (7x-2x)/10

40*10=5x

x= 400/5 = 80 pages

(1/5)*80= 16 pages

therefore pages left= 80-16=64

Answer 2

Answer:

Let the number of pages be x

According to the question,

1/5x + 40 = 7/10x

7/10x - 1/5x = 40

1/2x = 40

x = 40 * 2

x = 80 pages

Number of pages red by Reema = 1/5 * 80

= 16 pages

Number of pages left to read = 80 - 16 = 64 pages
