A large woven basket holds 30 ears of corn. A small woven box holds 6 ears of corn. How many ears of corn can be carried in 12 large baskets and 20 small baskets?

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
