Calculation of the Number of Musicians in the Folk Instruments Orchestra

To calculate the number of musicians in the folk instruments orchestra, we need to determine the difference in the number of male and female musicians compared to the symphony orchestra.

Let's assume that the number of musicians in the symphony orchestra is 39.

According to the given information, in the folk instruments orchestra, there are 15 fewer women and 19 more men compared to the symphony orchestra.

To find the number of musicians in the folk instruments orchestra, we can subtract 15 from the number of women in the symphony orchestra and add 19 to the number of men in the symphony orchestra.

Let's calculate it step by step:

Number of women in the folk instruments orchestra = Number of women in the symphony orchestra - 15 Number of men in the folk instruments orchestra = Number of men in the symphony orchestra + 19

Given that the number of musicians in the symphony orchestra is 39, we can calculate the number of musicians in the folk instruments orchestra as follows:

Number of women in the folk instruments orchestra = 39 - 15 = 24 Number of men in the folk instruments orchestra = 39 + 19 = 58

Therefore, the folk instruments orchestra consists of 24 women and 58 men. The total number of musicians in the folk instruments orchestra is 82.

Please note that the above calculation is based on the given information and assumptions.
