Say currently both a dozen eggs and 10 pounds of apples cost $50 (they are at the same price). So, to buy a dozen eggs and 10 pounds of apples we need$100.

After the increase, the price of a dozen eggs will be $55 and the price of 10 pounds of apples will be$51. So after the increase, to buy a dozen eggs and 10 pounds of apples we'll need $106. Increase = 6%.

An increase of 10% for the eggs would bring the new total to $11 An increase of 2% for the apples would bring the new total to$10.2
The original total is $20 and the new total is$21.2. Therefore the increase in price from the original to the new would be 1.2/20 = 6%. Answer: B

Say Cost of eggs = Cost of apples = 100

Total = 200

New egg cost = 110

New apple cost = 102

New total = 110 + 102 = 212

Percentage increase

$$= \frac{212 - 200}{200} * 100$$

= 6%

i used numbers to solve this one...
price for eggs = 1000$price for 10 pounds = 1000$
price for 1 pound = 100$new price for 1 pound = 102 -> for 10 - 1020 new price for dozen of eggs = 1100 total new price for dozen eggs and 10 pounds = 2120. this is 120 more than earlier. 120/2000 = 12/200 = 6/100. or 6% more.
