If (sin theta + cos theta)/(sin theta - cos theta)=7, then the value of tan theta is equal to :
(A) 4/3
(B) 5/3

• (sin theta + cos theta)/(sin theta - cos theta)=7
  or, 6 sin theta = 8 cos theta
  or, sin theta/cos theta = 8/6
  or tan theta = 8/6 = 4/3

• by componendo and devidendo
  
  a/b=c/d====(a+b)/(a-b)=(c+d)/(c-d)
  
  so by above expressiion tan(theta)=4/3
