(a) Rs10 (b) Rs15 (c) Rs20 (d) Rs25

• 2 oranges, 3 bananas and 4 apples cost Rs.15. 3 oranges, 2 bananas, and 1 apple costs Rs 10.
  the cost of 5 oranges, 5 bananas and 5 apples = 15+10=25
  the cost of 3 oranges, 3 bananas and 3 apples = 25*3/5=15

• 2x+3y+4z=15
  3x+2y+z=10
  -------------
  5(x+y+z)=25
  x+y+z=5
  3x+3y+3z=15

• b)15
  because (2+3)oranges,(3+2)bananas and (4+1)apples total cost=25..then the cost of 3oranges,3bananas and 3apples is Rs. 15.

• oranges=a,bananas=b,apples=c
  2a+3b+4a=15
  3a+2b+1c=10
  -----------
  5a+5b+5c=25=====>a+b+c=5 then 3(a+b+c)=3*5=15

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

• 2 o + 3 b + 4 a = 15
  3 o + 2 b + 1 a = 10
  ----------------------------
  Add both eqns....
  5(o+b+a)=25
  o+b+a=5
  cost of 3 o +3 b + 3 a = 3x5 = 15
