John bought three thermos flask at a total of st 1080 he later sold at 400 each what was his percentage

trasher [3.6K]

Answer:

$\boxed{ \bold{ \boxed{ \sf {11.11\%}}}}$

Step-by-step explanation:

Given,

Cost price of three thermos flask = 1080

Selling price of each thermos flask = 400

Finding the selling price of three thermos flask

Since, the cost of 3 thermos flask is more than that of 1 thermos flask. So, the cost of 1 thermos flask is multiplied by 3 ( i.e 400 × 3 = 1200 )

Here, the selling price is greater than cost price.

So, there is profit.

And we know that,

$\sf{profit = sp \: - \: cp}$

⇒ $\sf{1200 - 1080}$

⇒ $\sf{120}$

Profit amount = 120

Finding the profit percentage

$\sf{profit\% \: = \frac{profit}{cp} \times 100 \%}$

⇒ $\sf{ \frac{120}{1080 } \times 100\%}$

⇒ $\sf{11.11\%}$

Hope I helped!

Best regards!!
