Question

What would be the minimum number of notes for Rs 4849 if notes are available only in denominations of Rs 2, 5, 20, 50, 500?

A.

19

B.

20

C.

21

D.

22

Correct option is B


Solution:
Rs. 4849 ÷ 500 = 9 remainder 349.
So, we use 9 Rs. 500 notes, leaving us with Rs. 349 to be accounted for.
Rs. 349 ÷ 50 = 6 remainder 49.
So, we use 6 Rs. 50 notes, leaving us with Rs. 49 to be accounted for.
Rs. 49 ÷ 20 = 2 remainder 9. So, we use 2 Rs. 20 notes, leaving us with Rs. 9 to be accounted for.
Rs. 9 ÷ 5 = 1 remainder 4. So, we use 1 Rs. 5 note, leaving us with Rs. 4 to be accounted for.
Rs. 4 ÷ 2 = 2. So, we use 2 Rs. 2 notes.
Total number of notes used 9 notes of Rs. 500, 6 notes of Rs. 50, 2 notes of Rs. 20, 1 note of Rs. 5 and 2 notes of Rs. 2
Total = 9 + 6 + 2 + 1 + 2 = 20 notes
Thus, the minimum number of notes required is Option ( b) .
