we know he made a profit of 1834 for 200 shirts, let's divide those to see how much profit per shirt

so he made a profit of 9.17 per shirt, now profit is surplus value, value beyond the cost, we know its cost was 5.83 per shirt, so if we take 5.83 to be 100%, how much is 9.17 off of it in percentage?

Answer:
12
Step-by-step explanation:
1st of all we should let the ration of boys to girls be 2x and 3x.
After that we should make the sum between 2x and3×and the sum of 2numbers is equal to 30
i.e.2x+3x=30
Then ,by solving this eqation we get the value of x=6
After that put the value of x in the number of boys
i.e.
2x=2×6=12
Hence ,the number of boys is 12
