Question

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?

Answer 1

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.
