Let the price of one dozen of eggs and ten pounds of apples be P tk each.
So, total cost of one dozen of eggs and ten pounds of applles = P + P = 2P tk
New price of one dozen of eggs = P + 10% of P = P + 0.1P = 1.1P
New price of ten pounds of apples = P + 2% of P = 1.02P
Total new price of one dozen of eggs and ten pounds of apples = 1.1P + 1.02P = 2.12P
Price increase = (2.12P - 2P)/2P×100% = 6%
