2 oranges, 3 bananas and 4 apples cost Rs.15. 3 oranges 2 bananas 1 apple costs Rs.10. what is the cost of 3 oranges, 3 bananas and 3 apples?

(a) 30
(b) 15
(c) 10
(d) 20

• 2or+3ba+4ap=15--->(1)
  3or+2ba+1ap=10---->(2)
  (1)+(2)
  5or+5ba+5ap=15+10
  5(or+ba+ap)=25
  or+ba+ap=25/5
  or+ba+ap=5
  therefore 3or+3ba+3ap===>3(or+ba+ap);
  3(5)=15;

• B) 2oranges+3bananas+4apples=15
  Let each oranges cost 2rs. Each bananas cost 1rs. And each Apples cost 2rs.
  Then 2*2+3*1+4*2=15.... (I)
  And eqn II , 3*2+2*1+1*2=10
  Hence 3oranges, 3bananas and 3apples become 3*2+3*1+3*2=15

• 15 . orange +banana+apple= 5 .then 3(orange +banana+ apple)= 5*3
  Is nothing but 15

• 2 or + 3 ba + 4 ap = 9 fruits = 15 rupees
  3 or + 2 ba + 1 app = 6 fruits = 10 rupees
  3 or + 3 ba + 3 app = 9 fruits = 15 rupees

• 15,2x+3x+4x=15
  x=5/3
  3x+2x+x=10
  6x=10
  x=5/3
  3x+3x+3x=15

• 2o+3b+4a=15
  3o+2b+1a=10
  5o+5b+5a=25
  1o+1b+1a=5
  then multiply by 3
  ans is 15

• 2 o+3 b+a4 a=15 .....(1)
  3 o + 2 b + 1 a=10...(2)
  add equation 1 and 2
  we get the answer =15

• 2oranges+3bananas+4apples=15
  3oranges+2bananas+1apple=10
  ----------------------------------------------(Adding the whole equation)
  5oranges+5bananas+5apples=25
  Now,
  5(1orange+1banana+1apple)=25
  1orange+1banana+1apple=5
  
  Now,
  3oranges+3bananas+3apples
  3(1orange+1banana+1apple)=3x5=15(Ans)

• hi,
  
  i think
  
  it can be 15 bcoz
  
  2x+3y+4z=15
  
  3x+2y+z=10
  
  adding
  
  5x+5y+5z=25
  
  x+y+z=5 that is for 1 orange ,1 bannana and 1 apple requires 5Rs.
  
  so for 3 orange ,3 bannana and 3 apple requires 15Rs.
  
  i.e. 3x+3y+3z=15........
