What will be the Difference between the cost of 12 Cows and 36 Goats?

(1). The cost of 12 Cows and 36 Goats is Rs 1200.
(2). If the cost of cows is doubled, then Cost of 12Cows will be Equal to 72 Goats.

A- Can be answered using one of the statements but not the other.
B- Can be answered using either statements alone.
C- Can be ans using both statment together but cannot be answered using either statement alone.
D- Cannot be ans even using both statment together.

• A- Can be answered using one of the statements but not the other
  
  we have to find the value of (12c-36g)
  
  (1) The cost of 12 Cows and 36 Goats is Rs 1200
  12c + 36g = 1200 => c+3g=100
  from this we can't find the value (12c-36g)
  
  (2)If the cost of cows is doubled, then Cost of 12Cows will be Equal to 72 Goats
  12*(2c)=72*g
  => 12c = 36g
  => (12c-36g) = 0
  
  statement 2 is alone sufficient to find the value of (12c-36g)

• Option - A
  As in 2nd stm. assume cost of cow as 'c' and goat as 'g' now acc. to stm.
  12(2c) = 72g
  12c = 36g
  12c - 32g = 0
  which is the required answer.
  so it can be solved using statement 2 alone.

• Ans C
  12x+36y=1200 or x of 12 =100-3y
  12×2(100-3y)=72y or 2400=144y
  Y=200/12=50/3
  X=50
  Cost of 12=600
  Cost of 36=50/3×36=600
  Difference 0

• 12C + 36G=1200
  this means C+3G=100 - 1
  cost is doubled
  C1=2C then 12C1=72G -2
  C1=6Gbut C1=2C therefore
  2C=6G
  C=3G
  C-3G=0
  (C-3G)*12=12C-36G=0
  hence oply A

• answer A.
  1,statement is 12c+36g=1200
  so,1 is sufficent.,
  2.A/C
  12c*2=72g
  so we can write 12c-36g=0
  answer is A

• A
  Second statement will suffice

• option c is correct.. both the conditions are needed to find the difference.
• 10 years agoHelpfull: Yes(1) No(4)
• ans c
  after using both conditions(1 and 2)
  1 cow cost=50
  1 goat cost=50/3
  so 12cow cost -- 36 goats cost=0

• C- Can be ans using both statment together but cannot be answered using either statement alone.

• C)
  
  According to first statement 12x+36y=1200
  and 2nd statement 24x=72y
  2 unknown variables so we need both the equations to solve the question
• 10 years agoHelpfull: Yes(0) No(4)
• by statement 2, let the cost of cows are x, and cost of goats are y....if the cost of cows become double then,
  12*2x = 72y,
  x = 3y
  x-3y = 0 , now multiplyng wth 12,
  12x-36y = 0....(required ans can be found with statement 2 alone, statement 1 is not sufficient alone)...so, the ans is "A"...

• Answer : C
  
  Statement 1:
  12C + 36G = 1200
  C+3G = 100
  C=100-3G
  
  Statement 2:
  12*2*C = 72G
  C=3G
  
  Using (1) and (2)
  
  6G = 100
  G= 100/6 or 50/3
  C= 3*50/3 = 50
  
  Now see the difference in the cost of the two:
  
  12C - 36G
  12*50 - 36*(50/3) = 0
  Hence C is correct

• A BECAUSE STATEMENT 1 IS SUFFICIENT FOR THE ANS

• the ans is "a" bcos it can b solved using both statements together or only 2nd st.
