A) Rs. 25000
B) Rs. 20000
C) Rs. 15000
D) Rs. 22000
E) None of these
Let the total worth of the stock be Rs. x.   The SP of 20% of the stock = 1/5 * x * 1.1 = 11x/50   The SP of 80% of the stock = 4/5 * x * 0.95 = 19x/25 = 38x/50   Total SP = 11x/50 + 38x/50 = 49x/50   Overall loss = x - 49x/50 = x/50   x/50 = 400 =&gt; x = 20000   ANSWER:Rs. 20000
