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

• its too simple.add both equations.which will be 5o+5b+5a=25.now divide it by 5.
  o+b+a=5 so now multiply it by 3 3o+3b+3a=15
  so ans will be 15

• taking oranges = o apples = a bananas = a and adding both equations we get
  5o+5b+5a=25
  => 1o+1b+1a=5
  so 3o+3b+3a=15
  15 is the required answer.........

• 2x+3y+4z=15
  3x+4y+z=10
  solving above two equations
  2x+y=5
  (x,y) could be (1,3) or(2,1)
  for (1,3)
  2(1)+3(3)+4z=15
  z=1
  thus ans 15

• 2x+3y+4z=15
  3x+2y+z=10
  adding above 2 eq's
  5(x+y+Z)=25
  x+y+z=5
  we required 3x+3y+3z=?
  3(x+y+z)=3*5=15

• 2o + 3b + 4a = 15
  3o + 2b + a = 10
  now adding this two eqns & we get
  5(o + b + a) = 25
  o + b + a = 5
  so, 3(o + b + a) = 15...........

• 2o+3b+4a=15
  3o+2b+1a=10
  ------------
  5o+5b+5a=25
  ------------
  5(o+b+a)=25
  o+b+a=5
  3(o+b+a)=5*3
  3o+3b+3a=15 is the answer

• 15 rupees.1orange=rs 2,1 apple=rs 2,1 banana =rs 1.trial and error method we get rs 15

• a+b+c=5
  so 3*(a+b+c)=15

• adding the cost of 2cases give the cost of 1orange,1apple,1banana which is 5
  then for sum of 3 each is 15

• 2orange+3banana+4apple=15..eq1
  3orange+2banana+1apple=10..eq2
  eq1+eq2=25/5;
  3(orange+banana+apple)=15 ans.
