The error lies in adding what the friend kept to what the girls spent. If you subtract instead, you get the $55$ rupees that the mango merchant got. To add up the $60$ rupees, you need to add $57$ rupees that the girls actually paid and $3$ rupees that they initially paid but got back from the friend; or $55$ rupees that the merchant now has, $2$ rupees that the friend now has and $3$ rupees that the girls now have.
