Fruity Fruits
Ref : P2 Lesson 10
Strawberry is the lightest. Strawberry weighs 160g. Apple is the
heaviest. When I weigh 2 fruits at a time, the total mass are 410g, 540g and 630g. What is the total mass of the three fruit?
>>Solution
Strawberry (Lightest) + Pear = 410g
Pear = 410g – 160 g = 250g
Apple (Heaviest) + Pear = 630g
Apple = 630g – 250g = 380g
Total Weight : 160g + 250g + 380g = 790g
Answer : 790g
