Answer 1

Answer:

200pages

Step-by-step explanation:

{1/4+(1/3*3/4)}*x=100

(1/4+1/4)*x=100

1/2*x=100

x=100/(1/2)

x=100*2

x=200

therefore there are 200 pages in the book

Answer 2

Answer:

let total pages be x ....

1st day x/4

2nd day x/12 (4×3)

1st day +2nd day =100

x/4+x/12=100

3x+x=1200( by common lcm)

x= 400
