===========================

let total be X


=> Sonal read 2 by 5 of a book
=>2/5x

=>she find that there are still 120 PAGES left to be read

so  let us from an EQUATION

=>2/5 of x = 120


=>2/5 *x = 120


=>x = 120 *5/2

=>x = 600  / 2

=>x = 300 pages


so there are 300 pages


====================
lets check


2/5 of 300 pages


=>2/5 *300


=>600/5


=>120 pages
