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 ?.

• ANS=15
  let orange =x,banana=y,apple=z
  nw 2x+3y+4z=15 ------(1)
  3x+2y+z=10 ------(2)
  we have to find
  3x+3y+3z=?
  
  Add (1) and (2)
  we get 5x+5y+5z=25
  5(x+y+z)=25
  x+y+z=5
  3x+3y+3z=15

• 2x+3x=4x=15
  9x=15 than x=5/3
  3x+2x+x=10
  6x=10 than x=5/3
  now 3x+3x+3x=9x
  9*5/3
  ans: 15

• ANSWER 15
  
  2 O +3B +4A = 15
  
  3 O +2B + A = 10
  
  ADDING 5 O+5B +5A =25
  
  O + B + A =5
  
  3 O +3B +3A =15

• 2o+3b+4a=15.....(i)
  3o+2b+1a=10.....(ii)
  (i)+(ii)
  5*(o+b+a)=25
  =>(o+b+a)=5
  =>3o+3b+3a=15
