Shoes =20

One man =5

spectacle=2

Answer 2

Final Answer:

144

Solution:

We can solve the question step-by-step.

In the first equation it is given that:

1 pair of shoes + 1 pair of shoes + 1 pair of shoes = 60

That is:

3 pairs of shoes = 60

$\sf{1\:pair\:of\:shoes=\dfrac{60}{3}}$

$\sf{Value\:of\:one\:pair=20}$

One pair of shoes = 20

In the second equation, it is given that:

1 pair of shoes + man + man = 30

We know that the value of 1 pair is 20.

20 + 2 men = 30

2 men = 30 - 20

2 men = 10

$\sf{1\:man=\dfrac{10}{2}}$

$\sf{Value\:of\:man=5}$

Man = 5

In the third equation, it is given that:

spectacles + man + spectacles = 9

We know that the value of man is 5.

5 + 2 spectacles = 9

2 spectacles = 9 - 5

2 spectacles = 4

$\sf{1\:spectacle=\dfrac{4}{2}}$

$\sf{Value\:of\:one\:spectacle=2}$

Spectacles = 2

In the fourth equation, it is given that:

1 pair of shoes + 1 boxing glove + spectacles = 42

We know that:

 → 1 pair of shoes = 20

 → Spectacles = 2

20 + 1 boxing glove + 2 = 42

22 + 1 boxing glove = 42

1 boxing glove = 42 - 22

1 boxing glove = 20

In the last equation, we have:

1 shoe + 1 man x spectacles = ?

Exp.

If you notice the man, you would see that he is wearing a pair of shoes, a spectacles and a pair of boxing gloves. These all must be added to the value of the man.

 ✳ The single shoe

The value of a pair of shoes is 20.

So, the value of one shoe:

$\sf{=\dfrac{20}{2}=10}$

Hence the value of one shoe is 10.

 ✳ The man

The value of the man = 5

The value of the spectacles = 2

The value of the two boxing gloves = 20 x 2 = 40

The value of the shoes = 20

So, the total value of the man

= 5 + 2 + 40 + 20

= 7 + 60

= 67

The total value of the man is 67.

 ✳ The spectacles

The value of one spectacles is 2.

Therefore, the value of the equation is:

10 + 67 x 2

According to the BODMAS theorem, multiplication comes before addition.

So, we will solve the multiplication first.

= 10 + (67 x 2)

= 10 + 134

Now, we can add the values:

= 144

∴ The value of the last equation is 144.
