The correct option is A 3
We will solve the problem by repeated subtraction.
Out of the 12 candies, Anas filled the first packet with 4 candies.
The remaining candies =12−4=8
Now, Anas filled the second packet by another 4 candies.
The remaining candies =8−4=4
Finally, Anas filled the remaining 4 candies in the third packet.
Now, the remaining candies =4−4=0
So, 12 candies are distributed equally into 3 packets with 4 candies inside each.
