If total products are 50 grams and product A is 18 grams what is product B?

Answer and explanation

Correct answer: 32 grams

The total mass of the products is 50 grams, and product A accounts for 18 grams of that total. If the question assumes that the products listed are A and B, the mass of B is found by removing A’s mass from the total. In symbols, product B mass is \\(50-18=32\\) grams. This uses conservation of total mass within the stated two-product calculation.

Therefore option C, 32 grams, is correct. Adding 18 grams and 32 grams gives the stated total of 50 grams, which checks the result. The values 28 and 30 do not complete the total, while 68 grams would be larger than the total and cannot be the remaining amount. The supplied answer is consistent. The calculation depends on the natural reading that “total products” means only A plus B; under that intended school-MCQ reading, no revision is needed.
