Correct answer is 65
let Ravina's book has x pages and Kajal's book has y pages
i.e. 3x/4 + 17 = x-20
3x = 4(x - 28 - 17)
=4(x-45) = 4x - 180
x = 180
Ravina's book has 180 pages.
Kajal read 3/5th part and 20 pages and 26 pages are left
i.e. 3y/5 +20 = y - 26
3y = 5(y-26-20) = 5(y-46)
= 5y - 230
y = 230/2 = 115
Kajal's book has 115 pages
180-115=65
