Answer 1

Given:

3 pairs of shoes= 60

One pair of shoes+ 2 men= 30

Sunglasses+ 1 man+ sunglasses=9

2 pairs of shoes+ man= 42

To find:

What is:  A shoe+ a man with sunglasses x sunglasses??

Solution:

3 pairs of shoes = 60

3 × one pair of shoes = 60

one pair of shoes = 60/3

∴ one pair of shoes = 20

One pair of shoes + 2 men= 30

20 + 2 men= 30

2 men = 30 - 20

2 men = 10

man = 10/2

∴ man = 5

Sunglasses + 1 man + sunglasses = 9

Sunglasses + 5 + sunglasses = 9

5 + 2 sunglasses = 9

2 sunglasses = 9 - 5

2 sunglasses = 4

sunglasses = 4/2

∴ sunglasses = 2

A shoe+ a man with sunglasses x sunglasses

= 20 + (5 + 2) × 2

= 20 + 10 × 2

= 20 + 20

= 40

Answer 2

A shoe + A man with sunglasses × Sunglasses = 30

Step-by-step explanation:

3 pairs of shoes = 60

1 pairs of shoes = 60/3

∴ 1 pairs of shoes = 20

One shoe = 10

One pair of shoes + 2 men = 30

20 + 2 men = 30

2 men = 30 - 20

2 men = 10

men = 10/2

∴ men = 5

Sunglasses + 1 man + sunglasses = 9

2 sunglasses + 1 man = 9

2 sunglasses + 5 = 9

2 sunglasses = 9 - 5

2 sunglasses = 4

Sunglasses = 4/2

∴ Sunglasses = 2

A shoe + a man with sunglasses × sunglasses = 10 + (5 × 2) × 2 = 10 + 20 = 30
