Answer 1

Hint: If you need to answer these types of questions, then you need to be clear with the language. Unless and until you understand the question clearly, you will not be able to come up with a solution. In the question, we are given a word problem in which we are provided with the weight of a single two rupee coin and we are required to find the weight of a sack of coins containing a certain number of coins. So, we will multiply the weight of the coin by the number of coins to find the required weight of the sack.

Complete step-by-step solution:
So, we have a two rupee coin.
The weight of the two rupee coins is given to us as $6g$.
Now, we have to calculate the weight of a sack containing two rupee coins.
So, the number of coins in the sack is $2200$.
So, we can find the weight of a sack containing multiple two rupee coins by multiplying the number of coins by the weight of one single two rupee coin. So, we get,
Weight of sack containing $2200$ two rupee coins $ = 2200 \times 6g$
Carrying out the multiplication, we get,
$ = 13200g$
Therefore, the weight of the sack is $13200g$.
Hence, option (C) is correct.
