​

Answer 1

Answer:

1/5 + 3/10

= 2 + 3/10 (LCM = 10)

= 5\10 (or 250\500)

= 500 - 250 = 250 PAGES

Answer 2

Answer:

Books read by Rahul on the first day : 1/5 of 500 =100 pages

pages remaining :

500-100 = 400

Books read by Rahul on second day= 3/10 of 400= 120 pages

Remaining pages = 500-(100+120)

= 500-220

=280
