Question

Aman reads 1/3 of a book on Monday 1/2 of what is left on Tuesday and the remaining part on wednesday find the total number of pages in the book if he reads 100 pages on Wednesday​

Answer 1

let the number of pages in the book be x then

he read on Monday =

$\frac{1}{3} x$

now the remaining part

$x - \frac{1}{3} x$

this implies

$\frac{2x}{3}$

now he read on Tuesday

$( \frac{1}{2} ) \times \frac{2x}{3}$

$\frac{x}{3}$

remaining part

$\frac{2x}{3} - \frac{x}{3}$

$\frac{x}{3}$

noe according to the question

$\frac{x}{3} = 100$

$x = 3$
