Answer :
The number of yellow counters is 270.
We know that 3% of the counters are blue, which amounts to 27 counters. We need to determine the total number of counters in the bag. Let's denote the total number of counters by T.
Since 3% of the counters are blue, we set up the equation:
0.03 * T = 27
Solving for T by dividing both sides by 0.03, we get:
T = 27 / 0.03 = 900
Now, we know that the total number of counters is 900.
We are also given that 30% of the counters are yellow.
We calculate the number of yellow counters by:
0.30 * 900 = 270
