Given,
A sum of 100 rupees.
To find,
50 notes that make sum Rs 100 without using Rs 2.
Solution,
Let us assume that we have 25 notes with denomination ₹ 3.
The sum of 25 notes with ₹1denomination is = 3 × 25 = ₹75.
Now, let us assume that we have 25 notes with denomination ₹ 1.
The sum of 25 notes with ₹1 denomination is = 1 × 25 = ₹25.
Therefore, Total sum of money we got = ₹75 + ₹25 = ₹100.
Total notes used = 25 notes with ₹3 denominations and 25 notes with ₹1 denomination.
Hence, Total notes used are = 25 + 25 = 50.
