There are 325 pupils in a school choir at first. If the number of boys increases by 25 and the number of girls decreases by 5%, the number of pupils in the choir will become 341. How many boys are there in the choir at first ?

b = boys

g = girls = 325-b

 

b+25      +    .95(325-b)  =341      solve for b
