He need to eat 275 g

Answer 2

Correct Question

The total energy value of a 100 g cereal is 2000 kj. the boy requires 5500 kj of energy per day. How many grams of cereal does he need  to eat in order to obtain this energy.

Answer:

The quantity of  cereal does he need  to eat in order to obtain this energy is 275 g.  

Explanation:

Given:

The total energy value of a 100 g cereal is 2000 kj.

The boy requires 5500 kj of energy per day.

To Find:

The quantity of  cereal does he need  to eat in order to obtain this energy.

Solution:

As given-the boy requires 5500 kj of energy per day.

As given-the total energy value of a 100 g cereal is 2000 kj.

It means  $2000\ kj\ of \ energy = 100\ g\ of \ cereal$                

The quantity of  cereal does he need  to eat in order to obtain  5500 kj energy $=\frac{100}{2000} \times 5500\ g$

             $=275\ g$

Thus, the quantity of  cereal does he need  to eat in order to obtain this energy is 275 g.
