Hey mate here is the best answer you need I hope it is helpful to you please follow me and mark as brainliest

Step-by-step explanation:

We have learnt the unitary method. Using that we can find the cost of

1 gm jam in each bottle and compare. However,

the calculation is easier if we use a bigger

common factor rather than a smaller one.

Let us use 150, the HCF of 450 and 600 to

compare.

450 = 150 × 3, 600 = 150 × 4

∴ In the small bottle, 150 g of jam costs 96

3 = 32 rupees.

In the large bottle, 150 g of jam costs 124

4 = 31 rupees.

∴ Thus, it is more profitable to buy the 600 g bottle of jam

Answer 2

B jam bottle is more profitable to buy, because it cost less than the A jam bottle.

Given:

A shop sells a 450 g bottle of jam for Rs.96 and a 600 g bottle of jam for 120 Rs.  

To find:

Which of the bottles is more profitable to buy

Solution:

450 g of jam bottle A is sold at Rs.96

50 g of jam bottle A is equal to = 96/9

50 g of jam bottle A is equal to Rs.10.6

300 g of jam bottle A is equal to Rs.63.6

600 g of jam bottle B is equal to Rs.120

300 g of jam bottle B is equal to Rs.60

Result:

B jam bottle is more profitable to buy, because it cost less than the A jam bottle.
