Answer 1

$<b><i>Solutions:-$


We have,

Number of pages contain book = 280 pages
Naveen reads = 40% of total.
So, He reads = 40% of 280


Let the number of pages left be x


A/q

40% of 280 + x = 280

=> 40/100 × 280 + x = 280

=> 112 + x = 280

=> x = 280 - 112 = 168


Hence,
168 pages left to be read

Answer 2

Given :

Book contains = 280 pages

Completed 40% pages of the book .

100 - 40% = 60%

Still 60% is left to be read

280 x 60/100 = 168 .

Hence : Number of pages to be read are 168 .
