The correct answer is (B):
A total of 15% shirts are defective. Of the remaining 85%, 20% are sold in the domestic market. So, 20% of 85%, i.e. 17% are sold in the domestic market and the remaining 68% are exported. But, it is given that 8840 shirts were exported.
If 68% is 8840, 100% = (100)(8840)/68 = 13000.
