Correct Answer

Step 1: Let nn = number of notes of each type.

Step 2: Total value = 50n+100n=150n50n + 100n = 150n.

Step 3: Set up equation: 150n=750150n = 750.

Step 4: Divide by 150: n=5n = 5.

Answer: Ranju has 5 notes of ₹50 and 5 notes of ₹100. The total is 5×50+5×100=250+500=₹7505 \times 50 + 5 \times 100 = 250 + 500 = ₹750.
