To save money, Arkadelphia Cream Cheese will reduce each dimension of its rectangular box container (which is entirely full of cream cheese) by 25%, and reduce the price it charges its consumers by 25% as well. By what percentage does this increase the price-per-cubic-inch that each consumer will pay for cream cheese?
Choose the correct choice from the following options
A) 1. No change	B) 2. 78%	C) 3. 100%	D) 4. 300%	E) 5. 400%
Answer is 2. 78%   Take smart numbers   Let,   L = 20: 2. 78% = 10: H= 10 of initial box and Price = 100$   Therefore Price / cubic inch = 100 / (20*10*10)= 
<gadget id="calculator">100 / (20*10*10)</gadget>
<output>1/20 = around 0.05</output>
0.05   Now, when dimensions are reduced by 25% and price also reduced by 25%   L= 15; 2. 78%=7.5; H=7.5 and Price = 75$   Therefore price / cubic inch = 75 / (15*7.5*7.5) =0.089   Percentage change = (0.089 - 0.05) *100/ 0.025 = 78%
<result>B</result>
