Actually, there should be 11-bit DAC instead of 12-bit in the question.

So, R = (1/2^11 - 1) * 100 = 0.049.

Very simple.

R=(100/2048) which comes by the given formula below:

R=(1/2^n-11)*100

=>100/2^11

Actually there is no need of reference voltage for calculating percentage resolution its formula is R=(1/2^n-1)*100.

E(reference) is not given. How can we calculate Resolution without E(reference)?

I can't understood.
