Question

If 7 kg onions cost 140 rupees how much will we pay for 12 kg onions​

Answer 1

Answer:

240 rs

Step-by-step explanation:

here, it is given that,

cost of 7 kg onion = 140 rs

now, by unitary method, we have to find the cost of 1 kg of onion:

cost of 1kg onion = 140/7 = 20 rs

now,

cost of 12 kg of onions = 20 rs x 12 = 240 rs

therefore, the cost of 12 kg of onions is equal to 240 rs.
