Dear student ,

Probabely a calculating mistake has been done by you.

The solution follows as:

Total vol of ice cream from the cylinders=n*[ volume of one cone]

4*(22/7)*(21/2)*(21/2)*(38)=n {[(1/3)*(22/7)*(7/2)*(7/2)*(12)]+[(2/3)*(22/7)*(7/2)*7/2)*(7/2)]}

52668=n*(154+89.83)

n=52668/243.83=216.

Hence the correct answer is (c)
