Question 41 : cheese cubes are sold in packs of 60 crackers i sold in packs of 12 to make 60 snacks of two cheese cubes in one cracker what is the least number of packs of each type needed?

Option B is correct choice.

Step-by-step explanation:

We are told that cheese cubes are sold in packs of 60 and crackers are sold in packs of 12. We are asked to find the least number of packs of each type needed to make 60 snacks of two cheese cubes and one cracker.

We need 120 cheese cubes (60*2) and 60 crackers (60*1) to make 60 snacks. Now let us find the LCM of 12 and 60 to find least number of cracker packs.  

Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84, 96,...

Multiples of 60 are: 60, 120, 180, 240,...

We can see  LCM of 12 and 60 is 60. 12 times 5 is 60.

So we need at least 2 packs of cheese and 5 packs of crackers to make 60 snacks . Therefore, option B is the correct answer.

72 is the answer to this problem
