Answer:

The final answer is 4.76%

Step 1: To find the energy obtained in 1g of Cereal D, we divide the total energy by the total mass of cereal:

$\frac{1600}{100}$ = $16$ kJ/g

Step 2: Now we find the amount of energy obtained by consumption of 25g of Cereal D:

$25$ × $16$ = $400$ kJ

Step 3: Now we find this value as a percentage of the GDA of an average adult:

$\frac{400}{8400}$ × $100$ = $\frac{100}{21}$ = $4.76$ %
