Then, 3x = 15 or x = 5.
So, number of girls participating in sports = 2x = 10.
Number of students not participating in sports = 60 - (15 + 10) = 35.
Let number of boys not participating in sports be y.
Then, number of girls not participating in sports = (35 -y).
Therefore (35 - y) = y + 5 ⟺ 2y ⟺ 30 ⟺ y = 15.
So, number of girls not participating in sports = (35 - 15) = 20.
Hence, total number of girls in the class = (10 + 20) = 30.
In all the numbers except 383, the middle digit is the product of the other two digits.

Similarly, 32:112:(2/7)
32 ? 3 x 2 = 6
