Rs 10 1
Rs 5 1
Rs 2 2
Rs 1 1
so total is 8

Answer 2

Answer:

a. 8

Step-by-step explanation:

Suppose we want to generate maximum of Rs 99 from notes having denominations of 50, 20, 10, 5, 2, 1. Start from highest denomination

50- 1 note

20- 1 note

10- 2 notes

5- 1 note

2- 1 note

1- 2 note

Total- 1 note (50)+ 1 note (20)+ 2 notes (10) + 1 note (5) + 1 note (2) + 2 notes (1) = 8 Answer
