The cost of 3 bananas, 4 apples and 6 mangoes is Rs. 29 and the cost of 2 banas, 6 apples and 3 mangoes is Rs. 23. What is the cost of 7 bananas, 16 apples and 12 mangoes?

• Rs. 75
  
  Let cost of 1 banana, 1 apple and 1 mango be b, a and m respectively, then
  3b + 4a + 6m = 29 ---(i) and
  2b + 6a + 3m = 23 ---(ii)
  As we need cost of 7 bananas, 16 apples and 12 mangoes, so multiply equation (ii) by 2, we get
  4b + 12a + 6m = 46 ---(iii)
  Now adding equation (i) & (iii), we get 7b + 16a + 12m = 75
