Lets assume # T-shirts expected to sell = T , Price of each = p Hence, expected donation = Tp

(1) T = 1000 ; no info provided for p -------------->NS
(2) # T-shirts solds more than expected = t=500, Amont of money donated = 30000= (T+t)p = (T+500)p; no info provided for p & T -------------->NS
(1)+(2) T = 1000 , t=500, Hence 30000=(100+500)p => p =20
Hence 1st expected donation 20*1000=20000--------->S

Hence, Option C.
