29. Nutritional facts about a certain amount of food are as follows : It was found that 33.33% of the weight considered was proteins, 20% of the weight was carbohydrates and 25% of the weight was minerals. If the amount of vitamins in the food is 260 grams, and there is no other nutrient than these in the food, then what is the total weight of the food ?

• 1200.
  net fraction of vitamins=(1- (1/3)-(1/4)-(1/5))=13/60
  13/60 part is equiv to 260 grams
  so 1 full part is (260/13 *60) =1200.

• let the weight be x
  now a/c question
  33.33%ofx+20%ofx+25%ofx+260=x
  33.33x/100+20x/100+25x/100+260=x
  78.33x+26000=100x
  x=1199.81
  approx 1200
