Question

A 250g packet of iodised salt cost 150.
A 20kg sack of salt cost 10,400
Calculate the saving per kg by buying the 20 kg sack of salt

Answer 1

Answer:

Savings = Rs 1600

Step-by-step explanation:

250g = rs 150 ( multiply by 4 on both side to get the 1kg salt cost )

1000 g or 1 kg = rs 600

Now

20 kg = 600 x 20

= Rs. 12000

Given that 20 kg sack of salt = Rs. 10400

Savings = 12000 - 10400

= Rs 1600
