Answer:
2 packets
Step-by-step explanation:
∵ Number of chocolate cookies = 86,
Also, the number of sugar cookies = 42,
Since, 86 = 2 × 43,
42 = 2 × 3 × 7
HCF (86, 42) = 2
Now, if we want to create identical packages of cookies such that all cookies are used,
Then the greatest number of such packages = HCF(86, 42) = 2
