significant difference between selling quantity and GMP value in 58% of GMP value (t= 2.488, P< 0.05) and
both selling quantity and price were significantly different with GMP in 50% of GMP value. Selling price
and GMP are significantly different in 50% of GMP value (t=2.471, P< 0.05) and there was a significant
