Step-by-step explanation:
The digital scale has to be used once.
Let the coins that have normal weights are normal coins and the coins that has a weight 1 pound less are called defected coins.
5 stacks are there in which any four contains normal coins and 1 stack contains defected coins.
Took 1 coin from 1st stack, 2 coins from 2nd stack and so on..
Weigh the coins and see the result.
<u>If the total weight is 1 pound less than the stack 1 contains defected coin.</u>
<u>If the total weight is 2 pounds less than the stack 2 contains defected coin.</u>
<u>If the total weight is 3 pounds less than the stack 3 contains defected coin.</u>
<u>If the total weight is 4 pounds less than the stack 4 contains defected coin.</u>
<u>If the total weight is 5 pounds less than the stack 5 contains defected coin.</u>

Answer:
200 visitors went to screen 1.
125 visitors went to screen 2.
175 visitors went to screen 3.
Step-by-step explanation:
We will find number of visitors who went to screen 1 by finding 40% of 500 as we are told that 40% of 500 visitors went to screen 1.
Therefore, 200 visitors went to screen 1.
Now we will find number of visitors who went to screen 2. We are told that 25% of 500 visitors went to screen 2.

Therefore, 125 visitors went to screen 2.
Now we will find the number of visitors who went to screen 3 by subtracting combined number of visitors who went to screen 1 and screen 2 from total number of visitors.


Therefore, 175 visitors went to screen 3.
