Solution
The correct option is C ₹105
Cost of 1 kg onions = ₹30.
Cost of half kg onions = Half of ₹30
= ₹15
Cost of three kg onions = 30 × 3
= ₹90
Hence, the cost of three and a half kg onions = 90 + 15
= ₹105
Cost of 1 kg onions = ₹30.
Cost of half kg onions = Half of ₹30
= ₹15
Cost of three kg onions = 30 × 3
= ₹90
Hence, the cost of three and a half kg onions = 90 + 15
= ₹105
