if 1/a + 1/b + 1/c = 1/(a+b+c) where a+b+c !=(not equals) 0, abc != 0 , then what is the value of X=(a+b) (b+c) (c+a)+(a+b+c)?

• x = a+b+c
  because, (a+b)(b+c)(c+a) = 0

• Hii...REENA..Almost company hiring through overall marks cutoff.It depends on Company to company... Like Accenture hiring through overall score..It may be negative marking in any section..But finally you have score overall more than 100 marks as well as you have to also come under selected college list...And in word of CGI...This company will call if you have more than 50 Marks...!!!

  2 0 1 8 4 3 SO SIMPLY YOU HAVE TO PUT THE VALUE OF 1 AND 0.I CAN'T CALL BACK THE VALUE OF 0
  AND 1.
  Q.1 WAS:D*H*E=4*3*9=108
  Q.2 WAS:P*D*K=2*4*8= 64
  Q.3 WAS:X*P*__=5*2*1= 10 THE VALUE OF 1 CAN'T CALL FRIENDS.

  (ab+bc+ca)/abc=1/(a+b+c)
  => abc=a2b+ab2+ac2+a2c+b2c+bc2+3abc
  => a2b+ab2+ac2+a2c+b2c+bc2+2abc=0
  
  (a+b)(b+c)(c+a)=(ab+ac+b2+bc)(c+a)
  =abc+ac2+b2c+bc2+a2c+a2b+b2a+abc
  =0

• 1/a + 1/b = 1/(a+b+c) - 1/c
  
  (a+b)/ab = c-a-b-c/ (a+b+c)*c /* cross multiply*/
  
  After cancelling (a+b)
  
  1/ab = -1/[ (a+b+c)*c]
  
  Cross multiply
  
  (a+b+c)*c = -ab
  ac + bc + c^2 = -ab
  ac + ab + bc + c^2 = 0
  a(b+c) + c (b+c) = 0
  (b+c) * (a+c) = 0
  Hence value is 0

• Either >0 or

• a=-b will be the only case so (a+b)(b+c)(c+a) part will be zero. Hence it totally depends on the value of c. So either >0 or
