Seven girls each have seven cats. How many legs are there in the group?
63
210
49
196
Correct Answer : B
To calculate the total number of legs in the group, we need to consider both the legs of the girls and the legs of the cats.
Each girl has 2 legs. Since there are 7 girls:
7×2=14 legs from the girls
Each cat has 4 legs. Since each girl has 7 cats, there are a total of:
7×7=49 cats.
Thus, the total number of legs for the cats is:
49×4=196 legs from the cats.
Adding the number of legs from the girls and the cats gives:
14+196=210 legs in total
The correct answer is B 210.
