Question
If integrating factor of 
is 
then P is
Hint:
In this question we have to find the integrating factor of the given function. For this we will simplify the equation to bring it in the form dy/dx+Py=Q, where P and Q are the constants or functions of x. Then we can find the integrating factor using .
The correct answer is:

A given ray of light suffers minimum deviation in an equilateral prism P. Additional prisms Q and R of identical shape and material are now added to P as shown in the figure. The ray will suffer
As the prisms Q and R are of the same material and have identical shape they combine to form a slab with parallel faces. Such a slab does not cause any deviation.
