Answer 1

Answer:

(a) The cost of 1 kg of beans = ₹ 60

(b) the cost of 1 kg of cabbage = ₹ 20

(c) the cost of 7 kg of cabbage = ₹ 140

Step-by-step explanation:

The cost of beans is thrice that of cabbage.

Cost of 1 Kg of beans = Cost of 3 Kg of cabbage

Cost of 5 Kg of beans = Cost of 15 Kg of cabbage

Cost of 5Kg of beans + cost of 4 Kg of cabbage = ₹ 380

Cost of 15Kg of cabbage + cost of 4 Kg of cabbage= ₹ 380

Cost of 19Kg of cabbage = ₹ 380

Cost of 1 Kg of cabbage = 380 ÷ 19 = ₹ 20

Cost of 1 Kg of beans = 20 × 3 = ₹ 60

Cost of 7 Kg of cabbage = 20 × 7 = ₹ 140
