QUESTION: 11 The scales are balanced.
What is the value of the weight W in grams?

Solution:

W = 50g + 100 g + 250 g = 400 g

QUESTION: 12 The scales are balanced.
What is the value of the weight W in grams?

Solution:

W = 1 kg + 250 g = 1000 g + 250 g = 1250 g

QUESTION: 13 The scales are balanced.
What is the value of the weight W in grams?

Solution:

W = 250g + 750 g = 1000 g

QUESTION: 14 The scales are balanced.
What is the value of the weight W in grams?

Solution:

W = 50g + 250 g = 300 g

QUESTION: 15 The scales are balanced.
What is the value of the weight W in grams?

Solution:

W = 100g + 250 g = 350 g

QUESTION: 16 The scales are balanced.
What is value of the weight W in grams?

Solution:

W = 250g + 250 g = 500 g

QUESTION: 17 The scales are balanced.
What is the value of the weight W in grams?

Solution:

W = 50g + 500 g = 550 g

QUESTION: 18 The scales are balanced.
What is value of the weight W in grams?

Solution:

W and 500 g together balance with 750g
So W must be 750g − 500 g = 250g.

QUESTION: 20 The scales are balanced.
What is the value of the weight W in grams?

Solution:

W = 250g + 500 g = 750 g
