Please answer the following question by reasoning step-by-step.
There are 11 boys and 13 girls in a class. If 1 boy is added to the class, what percentage of the class are girls?

52
There are a total of 11 + 1 = 12 boys in the class.

Hence, there are a total of 12 boys + 13 girls = 25 students in a class.

So 13 / 25 x 100% = 52% of the class are girls.

.

So, the final answer is 52
