Answer: Hence, the correct size of boys group is 5 and girls is 6.
Step-by-step explanation:
Since we have given that
Number of boys = 60
Number of girls = 72

For this we will find "HCF of 60 and 72" which is equal to "12".
So, the correct size of each group is 12 in which number of boys would be 
Number of girls would be 
Hence, the correct size of boys group is 5 and girls is 6.
