Cost of 1 kg onion and 3 kg carrots?
Answers
Answer:
(a) Cost of 1 kg tomatoes = Rs 8
∴ Cost of (1/2) kg tomatoes = Rs 8 ÷ 2 = Rs 4
(b) Cost of 1 kg onions = Rs 10 Cost of 1 kg carrots = Rs 16
∴ Cost of (1/2) kg onions = Rs 10 ÷ 2 = Rs 5 And, Cost of (1/4) kg carrots = Rs 16 ÷ 4 = Rs 4 The cost of (1/2) kg onions is more than the cost of (1/4) kg carrots.
(c) Cost of 1 kg potatoes = Rs 12 Cost of (1/4) kg carrots = Rs 12 ÷ 4 = Rs 3
∴ Cost of (3/4) kg potatoes = Rs 3 × 3 = Rs 9
(d) Keerthi has Rs 20. Her shopping list includes (1/2)kg potatoes, 2 kg pumpkins and (1/4) kg carrots. Cost of 12kg potatoes = Rs 12 ÷ 2 = Rs 6 Cost of 2 kg pumpkins = Rs 2×4 = Rs 8 Cost of (1/4) kg carrots = Rs 16 ÷ 4 = Rs 4 Total cost of all vegetables = Rs 6 + Rs 8 + Rs 4 = Rs 18 Keerthi can purchase all the vegetables in her shopping list, as she has Rs 20.
