Question 5: How many different sums of money can be formed from the four type of notes Rs 10, Rs 20, Rs 50 and Rs 100 ?

The question is asking for the number of different sums of money that can be formed using four types of notes: Rs 10, Rs 20, Rs 50, and Rs 100.

Here are the steps to solve this problem:

Step 1: Understand the problem We have four types of notes and we can use any number of each type of note to form a sum. The question is asking for the number of different sums that can be formed.

Step 2: Identify the possible sums The smallest sum we can form is Rs 10 (using one Rs 10 note). The next smallest sum is Rs 20 (using two Rs 10 notes or one Rs 20 note), and so on.

Step 3: Count the number of different sums This is a bit tricky because we have to consider all possible combinations of notes. However, since there is no limit to the number of each type of note we can use, we can form an infinite number of different sums.

For example, we can form Rs 30 by using three Rs 10 notes, or one Rs 10 note and one Rs 20 note, or one Rs 20 note and two Rs 10 notes, and so on. Similarly, we can form Rs 40, Rs 50, Rs 60, and so on, each in multiple ways.

Therefore, the answer is that an infinite number of different sums can be formed.
