Let $5 bills be 2x,$1 bills would be=x (as $5 bills are 2 times more)$10 bills would be=2x+2 (as $10 bills are 2 more than $5)so on adding all bills and multiplying its face value, we get,5(2x)+1(x)+10(2x+2)=8210x+x+20x+20=8231x+20=8231x=62x=2
thus $1 bills are-2, $5 bills are-2(2)=4 and $10 bills are-2(2)+2=6
hope this helps!
