Answer:
90 people
Explanation:
Let's find the total number of ladels of soup.
1 person ----- 3 ladles
150 people ----- 3 ×150= 450 ladles
The amount of soup cooked does not change. Since now more soup is given to each person, the number of customers fed would decrease.
Number of people fed
= 450 ÷5
= 90
