A shopkeeper sells 20% of his stock at 20% profit ans sells the remaining at a loss of 10%. He incurred an overall loss of Rs. 400. Find the total worth of the stock?	Options
A) 15500
B) 16000
C) 15000
D) 17000
E) 20000
Let the total worth of the stock be Rs. x.   The SP of 20% of the stock = 1/5 * x * 6/5 = 11x/50   The SP of 80% of the stock = 4/5 * x * 0.90 = 19x/25 = 36x/50   Total SP = 12x/50 + 36x/50 = 48x/50   Overall loss = x - 48x/50 = 2x/50   2x/50 = 600 =&gt; x = 15000   Answer:15000
