NASA's MAVEN payload was just 4.3 times heavier (65kg vs. 15kg) but cost 9.1 times more ($671M vs. 74M).
So NASA is still 2.1 times more expensive per kg of useful payload. And costs scale less than linearly with the payload mass, so a bigger Indian mission would have likely been even more than 2.1 times more efficient than NASA...
