Answer 1

Hey Dear !

_______________________________

Let Book contains x no. of pages

I read 4/9 of x on one day

And 3/5 of x on one day

100 pages still remains to read

ATQ

\frac{4x}{9} + \frac{3x}{5} + 100 = x

\frac{20x + 27 x + 4500}{45} = x

\frac{47x + 4500}{45} = x

47x + 4500 = 45x

2x = 4500

x = 4500/2 = 2250
