I was attempting the following problem. enter image description here In

In the question it says there is a non inverting amplifier with a feedback resistor of 100k ohms and a source resistor of 5k ohms. If I use the regular non-inverting op amp formula for the gain I get 21 V/V as the answer. 

But in the question itself it also says that the gain of the amplifier is 10 V/V. So which is it? 

Also do they mean when they say that the gain is 10V/V, that the gain after removing the output voltage consumed by the input bias current and the off set current. Thanks in advance.
