In parallelogram ABCD , what is the measure of ∠ADC?

(1) The measure of ∠ABC is greater than 90
(2) The measure of ∠BCD is 70



(1) This leads to several possible answers, hence insufficient.

(2) ∠BCD + ∠ADC = 180 As we already know that the first one is 70, the second is 180-70. Thus, sufficient.

In order to get clarity on such questions, we have a targeted quant course for candidates preparing for the GMAT. You can find more details here:

You can also opt for a well rounded course catering to all the needs of GMAT prep: https://www.optimus-prep.com/gmat-on-demand-course

Feel free to take a 7 day trial of the courses we offer.
