Niharika is practicing her dance steps along with her friends. In a particular sequence, all of them form a row. At that point, Niharika is standing on the 4th position from either end of the row.

Can you find out how many girls are practicing together?

7

As Niharika is 4th from either end of the row, it means that 3 girls are on one of her sides and 3 are present on the other.

3 + 3 + 1(Niharika herself) = 7.

Hence, 7 girls are practicing the dance together.
