Bill has d animals, 16 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?	Options:	A) 6	B) 12	C) 18	D) 24	E) 36
Total d animals, suppose each has price of x - total price = dx   now 16 were sold at profit of 10%, making equation - - 16*1.1x   now d-16 were sold at loss of 20%, making eqn --- (d-16)*0.8x   Now he made no profit or loss so,   dx = 16*1.1x + (d-16)*0.8x   solving for d, we get d=24   Ans 24
