The sum of intercepts of the plane on the coordinate axes is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Equation of plane 4x+3y+2z=2 xa+yb+zc=1 is intercept form a=x intercept b=y intercept c=z intercept ⇒4x+3y+2z=2 ⇒4x+3y+2z2=1 ⇒4x2+3y2+z=1 ⇒x12+y23+z1=1 a=12,b=23,c=1 Hence, a+b+c=136.
