4x + x = 150, x=30 (shorter piece)
5x=150
x=150/5 = 30
4x=120
x=30
total = 150

Number of ways in which the 3 can be selected from 13 = 286
Step-by-step explanation:
Step 1:
Number of books considered by the textbook search committee = 13
Number of books selected from this 13 = 3
We need to determine number of ways in which the 3 can be selected from the 13
Step 2 :
The order of the 3 books selected does not matter. So,
Number of ways in which the 3 books can be selected from 13 books = C(13,3) = 
=
=
= 286
Step 3 :
Answer :
Number of ways in which the 3 can be selected from 13 = 286
