. 2 oranges, 3 bananas and 4 apples cost Rs.15. 3 oranges, 2 bananas, and 1 apple costs Rs 10. What is the cost of 3 oranges, 3 bananas and 3 apples?
(a) Rs10 (b) Rs15 (c) Rs20 (d) Rs25

• 2 oranges + 3 bananas + 4 apples = 15/-
  
  3 oranges + 2 bananas + 1 apples = 10/-
  
  add the above two equations:
  
  5 oranges + 5 bananas + 5 apples = 25/-
  
  so we get:
  
  1 orange + 1 banana + 1 apple = 5/-
  
  finally:
  
  3 oranges + 3 bananas + 3 apples = 15/-
