Questions  

 The line xa+yb=1 meets the x -axis at A and y -axis at B and the line y=x at C such that the area of the AOC is 

 twice the area of ΔBOC . Then the coordinates of C are 

a
b3,b3
b
2a3,2a3
c
2b3,2b3
d
None of these

detailed solution

Correct option is C

Given ΔAOC=2ΔBOC⇒ 12(OA)x1=2×12(OB)x1⇒ a=2b Equation of AB⇒xa+yb=1----(1)x2b+yb=1----(2)⇒ Since point C lies on the line (2)⇒ x12b+x1b=1⇒ x1=2b3=a3⇒C=2b3,2b3
