A vendor bought each apple for $3/2 = $<<3/2=1.50>>1.50.
He will sell each apple at $10/5 = $<<10/5=2>>2 each.
His profit for each apple is $2 - $1.50 = $<<2-1.5=0.50>>0.50.
His total profit for 5 apples is $0.50 x 5 = $<<0.50*5=2.50>>2.50.
He bought each orange for $2.70/3 = $<<2.7/3=0.90>>0.90.
His profit for each orange is $1 - $0.90 = $<<1-0.9=0.10>>0.10.
His total profit for 5 oranges is $0.10 x 5 = $<<0.10*5=0.50>>0.50.
Therefore, his total profit for selling 5 apples and 5 oranges is $2.50 + $0.50= $3.
