Question

The average salary of a group of unskilled workers is 10000and skilled workers is 15000. If the combined salary is 12000 what is the percentage of skilled workers​

Answer 1

Let x be unskilled and y be skilled

According to the question,

10000x+15000y=12000x+12000y

2000x = 3000y

By solving this equation we will get,

2x = 3y

Skilled workers is 2x/3

Total workers x + 2x/3 = 5x / 3

Percentage of skilled = 2x/3 divided by 5x/3 = 40%

Therefore, 40% answer is the percent of skilled workers.
