Question

priya read 3/8 of a book in one day and 2/5 of the remaining the next day . if 156 pages of the book were still left unread , how many pages did the book contain​

Answer 1

Answer:

let the total no of pages be x.

the no of pages read on 1st day = 3/8x

no. of pages left = 5/8x

no of pages read on next day = 5/8x × 2/5 = 1/4x

A/q

3/8x + 1/4x +156 = x

x - 3/8x - 1/4x = 156

(8x-3x-2x)/8 =156

3x/8 = 156

x= 156×8/3

x = 416

Step-by-step explanation:

Answer 2

3x = 156×8

x = 156×8/3

= 52×8

= 416 (ans)

Hence, the book contains 416 pages in total..
