In a row of 50 books, Book A is 15th from left and Book B is 20th from right. How many books lie between them?

A17

B15

C12

D10

Answer:

B. 15

Read Explanation:

Total books = 50

  • Book A is 15th from the left.

  • Book B is 20th from the right.

Position of Book B from the left:

(50 - 20 + 1 = 31)

So, Book A is at position 15 and Book B is at position 31.

Books between them:

(31 - 15 - 1 = 15)

Therefore, 15 books lie between them.
