Question

find the gain or loss per cent of following cp=720 sp=640​

Answer 1

Answer:

Loss percentage is 11.11% .

Step-by-step explanation:

Given -

CP = ₹ 720

SP = ₹ 640

Find gain or loss percentage.

As,

SP is less than CP So, loss occurred.

We know that,

Loss percentage = $\frac{cp - sp}{cp} \times 100$

Where,

SP= Selling price

CP = Cost price

Loss percentage = $\frac{720 - 640}{720} \times 100$

Loss percentage = $\frac{80}{72} \times 10$

By dividing 80 and 62 by 8 we get

Loss percentage = $\frac{10}{9} \times 10$

Loss percentage = $\frac{10 \times 10}{9}$

Loss percentage = $\frac{100}{9}$

Loss percentage $= 11.11$

Hence,

Loss percentage is 11.11% .
