Rs 120

Rs 100

Rs 135

Rs 150

Rs 60

Solution:

Profit = Selling Price – cost price

CP of 3 books = SP of 12 books – CP of 12 books

CP of 15 books = SP of 12 books

CP of 15 books = 1800

CP of 1 book = 1800/15

= Rs 120

CP of 3 books = SP of 12 books – CP of 12 books

CP of 15 books = SP of 12 books

CP of 15 books = 1800

CP of 1 book = 1800/15

= Rs 120

Required probability = 15/36

= 5/12

Favorable event = [(1, 1), (1, 2), (1, 4), (1, 6), (2, 1), (2, 3), (2, 5), (3, 2), (3, 4), (4, 1), (4, 3), (5, 2), (5, 6), (6, 1), (6, 5)]
