यदि `a+b+c=0` तो `((a+b)/c+(b+c)/a+(c+a)/b)(a/(b+c)+b/(c+a)+c/(a+b))` का मान ज्ञात करें।

Options

A. 8
B. -3
C. 9
D. 0

Answer

C

Explanation

`a+b+c=0`
Have values
`a=1`
`b=2`
`c=-3`
`implies((a+b)/c+(b+c)/a+(c+a)/a) (a/(b+c)+b/(c+a)+c/(a+b))`
`implies ((1+2)/(-3)+(2-3)/1+(-3+1)/2)(1/(2-3)+2/(-3+1)+(-3)/(1+2))`
`implies (-1-1-1)(-1-1-1)`
`implies -3xx -3=9`
