Question

find gain or loss %for (i) cp=120 sp= 80​

Answer 1

$\huge \underline \bold \pink{Solution : }$

Given that :

C. P = 120

S. P. = 80

Since C. P. > S. P. then there will be loss

As we know that :

Loss = C. P. - S. P.

=> Loss = 120 - 80 = 40

Now, Loss% = (Loss/C.P.) × 100

=> Loss% = 40/120 × 100

=> Loss% = 100/3 = 33.33%

So, the loss% will be 33.33% ✔✔

Answer 2

Given:

• CP (Cost Price) = Rs. 120
• SP (Selling Price) = Rs. 80

What To Find:

We have to find,

• Find the gain or loss %.

How To Find:

To find it, we have to

• First, find whether it is the gain or loss.
• Next, find the gain or loss.
• Then, find the gain or loss %.

Solution:

• Finding whether it is a gain or loss.

If SP > CP, then it is a gain.

If CP > SP, then it is a loss.

Here,

• CP = Rs. 120
• SP = Rs. 80

As it CP > SP.

∴ Therefore, it is a loss.

• Finding the loss.

To find loss, we have to use,

⟶ Loss = CP - SP

⟶ Loss = 120 - 80

⟶ Loss = Rs. 40

• Finding the loss %.

Using the formula,

⟶ Loss % = (Loss ÷ CP) × 100

Substitute the values,

⟶ Loss % = (40 ÷ 120) × 100

Cancel the zeros,

⟶ Loss % = (4 ÷ 12) × 100

Simplify 4 ÷ 12,

⟶ Loss = 1/3 × 100

Multiply 1 with 100,

⟶ Loss = 100 ÷ 3

Divide 100 by 3,

⟶ Loss = 33.33 %

Final Answer:

∴ Thus, the loss % is 33.33 %.
