Answer:21 Rs 60 paisa

Step-by-step explanation:the cost of 3 1/2 kg of sugar= 63Rs

so, the cost of one kg of sugar = 7/2=2/7×63= 18Rs.

So the cost of 1 1/5 kg of sugar will be= 18+1/5 of 18

18+3.60

21 Rs 60 paisa

Step-by-step explanation:3 1/2 kg = 7/2kg = 7/2×1000 g = 3500g

1 1/2kg = 3/2kg = 3/2 x 1000g = 1500g

cost of 3500g of sugar is rs. 63

cost of 1g of sugar is rs. 63/3500

cost of 1500g of sugar is 63/3500×1500.

= rs.27
