The Use of LCM and HCF
Example A shop sells a 450 g bottle of jam for 96 rupees and a bigger bottle of
600 g for 124 rupees. Which bottle is it more profitable to buy?
olution: 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.
