Choose the correct option.
A) Rs. 21000 B) Rs. 17500 C) Rs. 19000 D) Rs. 24500 E) None of these
Let the cost prices of the colour television sold at 30% profit and 40% profit be Rs. x and Rs. (35000 - x) respectively.   Total selling price of televisions = x + 30/100 x + (35000 - x) + 40/100 (35000 - x)   =&gt; 130/100 x + 140/100 (35000 - x) = 35000 + 32/100 (35000)   x = 28000   35000 - x = 7000   Difference in the cost prices of televisions = Rs. 21000   Rs. 21000NSWER:Rs. 21000
