Let

u(x)

and

v(x)

are differentiable functions such that

\frac{u(x)}{v(x)}=7

. If

\frac{u^{\prime}(x)}{v^{\prime}(x)}=p

and

\left(\frac{u(x)}{v(x)}\right)=\mathrm{q}

, then

\frac{p+q}{p-q}

has the value equal to :

View answer and explanation

Correct option: A

Option A (1) is correct because after differentiating and simplifying, the value of (p+q)/(p-q) is found to be 1.
