Bill has d animals, 32 of which were sold at a profit of 10% each while the rest were sold at a loss of 20% each. Overall, Bill made neither a profit nor a loss. Which of the following is equal to d?	Choose one:
A) 6 B) 12 C) 18 D) 24 E) 48
Total d animals, suppose each has price of x - total price = dx   now 32 were sold at profit of 10%, making equation - - 32*1.1x   now d-32 were sold at loss of 20%, making eqn --- (d-32)*0.8x   Now he made no profit or loss so,   dx = 32*1.1x + (d-32)*0.8x   solving for d, we get d=48   Ans 48
