If square of (a-b) = 1, square of (a+b)=25. then the value of a and b
1. |a|>|b|
2. a=3
as per e-litmus (I don't remember it clearly)
a) only one is sufficient and other is not required
b) using any solution can be obtained
c) both statements are required
d) not any statement is sufficient
options:-
1. b 2. d 3. a 4. c

• a+b=(+5,-5)
  a-b=(+1,-1)
  so we will have 4 equations
  on solving these equations
  a,b=(3,2)
  a,b=(2,3)
  a,b=(-2,-3)
  a,b=(-3,-2)
  
  Now in second statement it is given that a=3. that is sufficient to given the values as 3,2.
  hence option 3 is correct.

• if we take statement 2 we can say that if a=3 then b=2 must.
  but statement 1 there are two possible solution so using 1st statement we can not give the answer.
  but in 2nd is sufficient so answer is option a

• both are not sufficient to answer the question
  because
  a+b=(+5,-5)
  a-b=(+1,-1)
  so we will have 4 equations
  on solving these equations
  a,b=(3,2)
  a,b=(2,3)
  a,b=(-2,-3)
  a,b=(-3,-2)

• Any one statement is sufficient

• nopes
  equation is is
  (a+b)^2=1
  (a-b)^2=25

• only one statement is sufficient. |a|>|b|
• 9 years agoHelpfull: Yes(0) No(0)
• Either I or II follows
  In first statement if a=3 and b=-2
  (a+b)^2=1
  (a-b)^2=25

• Ans: d
  there are four combination (2,3),(3,2),(-2,-3),(-3,-2)

• only 1 will be sufficient...
