Hint: We are given the weight of a shark and the weight of one child. We are asked in the question to find the difference in the weight of a shark and the weight of 12 children put together. So, we are given the weight of one child, which is, $15kg$ and so the weight of 12 such children will be the product of 12 and weight of one child and so we will have the total weight of the child. We will then subtract the weight of the shark and the weight of 12 children. Hence, we will have the required difference.

Complete step-by-step solution:
According to the given question, we are given the weight of the shark, which is, $200kg$ and the weight of one child, which is, $15kg$. We are then asked to find the difference between the weight of the shark and the weight of 12 children.
We are given,
Weight of one child = $15kg$
Weight of 12 children = $12\times 15$
$\Rightarrow$ Weight of 12 children = $180kg$
Now, we have the given weight of the shark = $200kg$
The difference in the weight of the shark and 12 children together, we have,
$\Rightarrow 200-180$
$\Rightarrow 20kg$
Therefore, the weight of the shark is $20kg$ more than the weight of 12 children together.
Note: The weights of the shark and of the children should not get intermixed. Also, while finding the weight of 12 children, we are assuming that all the children taken into consideration are of $15kg$ each. While subtracting the weight of children from the weight of shark, make sure that the calculation is done correctly.
