Question

Peter is reading a 193-page book. he has read three pages more than one fourth of the number of pages he ahsn't read yet.

Answer 1

Let the number he hasn't read yet be X
pages he has read = 3 + ¼x
so 3+¼x +x = 193
5/4x = 193-3 = 190
5x = 190×4 = 760
x= 760÷5 = 152

a. number of pages he hasn't read yet is 152
b if he reads 8 pages in 1 day
then he'll read 152 pages in 152/8 days = 19days
