My entries in the payables account:

Dr.(purchases) 2400
Dr. (Discount) 11200
Cr: (Purchases) 942850
C/F: 171250
B/F: 130400

In the purchase account:
Dr (payables) : 942850
Cr (Drawings): 1000
Cr:(Payables): 2400
SOPL: 939450

In the Discount received:
Cr(Payables): 11,200

Net purchases:

However the answer is:937050. Can you explain, how this answer comes?
