Question

Weight of sugar in each teaspoon is 15 grams. Each glass of lemonade required 2.5 teaspoons of sugar. How many grams of sugar is required for 12 glasses of lemonade?

• A. 440 grams
• B. 450 grams
• C. 800 grams
• D. 900 grams

Answer 1

The correct option is B 450 grams

Weight of sugar in each teaspoon = 15 grams
Number of teaspoons required for one glass of lemonade = 2.5
Total weight of sugar in each glass of lemonade = 2.5 × 15 grams
We will put back the decimal point after one point from the right.
So, 2.5 × 15 = 37.5
So, the total weight of sugar in each glass of lemonade = 37.5 grams.

Total number of glasses of lemonades = 12

Total weight of sugar in 12 glasses of lemonade = 12 × 37.5 grams

We will put back the decimal point after one point from the right.
So, 12 × 37.5 = 450.0 = 450

Thus, the total weight of sugar required to make 12 glasses of lemonade is 450 grams.
