Based on the ratio, 6 students play musical instruments.
The mentioned problem can be solved using the concept of ratio and proportion. We will equate the two ratio. Let us assume the number of students who play musical instruments be x.
Forming the equation -
3 : 20 = x : 40
Rewriting the equation with respect to x
x = (40 × 3) ÷ 20
Performing multiplication and division on Right Hand Side of the equation
x = 120 ÷ 20
Performing division on Right Hand Side of the equation
x = 6
Therefore, 6 students play musical instruments.
