Answer:
5 1/2 kg = ₹ 100 per kg
3 1/4 kg = ₹ 200 per kg
Total cost of Barfi = 5 1/2 *100
= 11/2 * 100
= 550
Total cost of rosmallai = 3 1/2 *200
= 13/4 *200
= 650
Total cost of sweets = ₹ 550 + ₹ 650
= ₹ 1200
Praveen give 3 notes of ₹ 500 ( 3 * 500 = 1500)
i.e ₹ 1500
Money refunded to Praveen
= ₹ 1500 - ₹ 1200
= ₹ 300 ans.
