Answer:
<em>56 adult tickets were sold</em>
Step-by-step explanation:
Ratio of ticket sold to Children and adult is in the ratio 4 : 7
Total ratio = 4 +7 = 11
Ratio of adult = 7
Total ticket sold = 88
Number of adult tickets sold = Ratio of adult/Total ratio * Total ticket sold
Number of adult tickets sold = 7/11 * 88
Number of adult tickets sold = 7 * 8
Number of adult tickets sold = 56 tickets
<em>Hence 56 adult tickets were sold</em>
