Answer:
We have 6 books of Economics, 3 of Mathematics and 2 of Accountancy
Arranging the books within the branches:
Economics - 6!
Maths - 3!
Accountancy - 2!
Thus the arranging branches are 3!
Thus, total arrangement
6!×3!×2!×3!=32,400
For 2: We have to add all the books together then arrange it
6+3+2=11
Thus the total arrangement are:
11!
