Which costs more: $\frac{1}{3}$ kg of onions or $\frac{3}{5}$ kg of carrots?

Price of 1 kg of onions = ₹30
Price of 1 kg of carrots = ₹15

The correct option is B $\frac{1}{3}$ kg onions
Cost of 1 kg onion = ₹30
Cost of ⅓ kg onion = ₹30 ÷ 3 = ₹ 10

Cost of 1 kg carrot = ₹15
Cost of ⅕ kg carrot=⅕ of ₹15= ₹15 ÷ 5 = ₹3
Cost of ⅗ kg carrot = 3× ⅕ kg of carrot = 3 × ₹3 = ₹ 9

As ₹ 10 > ₹ 9
Cost of ⅓ kg Onion > Cost of ⅗ kg Carrot
