During the first quarter of the year, 351,875 people downloaded an an app for their smartphones. during the second quarter of the year, 101,949 fewer people downloaded the app than the first quarter. how many downloads occurred during the two quarters of the year?

 351,875 - 101,949 = 249,926

351,875 + 249,926 = 601,801

If you subtract 351,875 from 101,949 you will come up with 249,926.

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
