Discussion

Explanation:

Since the weight of the cake was as heavy as possible, it can be obtained by finding the H.C.F. of the three fractions.

To calculate HCF of fractions, first we need to simplify the fractions and then, HCF of fractions = HCF of NumeratorsLCM of Denominators

∴H.C.F53,234, 75 = HCF(5,23,7)LCM(3, 4, 5) = 160 

Now, since each guest received 1/60 lbs of cake,

The number of guests who attended the party = 53+234+2115160 = 529.

Hence, 529.
